extensions: load help from hgext.__index__ as a fallback this time

Prior to 843418dc0b1b, `hgext.__index__` was consulted first if present, which
caused the longer help from the extension modules to be ignored, even when
available.  But that change causes a bunch of test failures when the pyoxidized
binary bundles *.pyc in the binary, saying the there's no help topic for
`hg help $disabled_extension` and suggesting the use of `--keyword`, rather than
showing a summary and indicating that it is disabled.  Current failures were in
test-check-help.t, test-extension.t, test-help.t, and test-qrecord.t.

Ideally, we would read the various *.pyc files from memory and slurp in the
docstring, but I know that they used to not be readable as resources, and I
can't figure out how to make it work now.  So maybe 3.9 and/or the current
PyOxidizer doesn't support it yet.  I got closer in py2exe with
`importlib.resources.open_binary("hgext", "rebase.pyc")`, but `open_binary()` on
*.pyc fails in pyoxidizer.[1]  Either way, the *.pyc can't be passed to
`ast.parse()` as `extensions._disabledcmdtable()` is doing, so I'm setting that
aside for now.

  changeset 3398603c5621: unexpected block in release notes directive feature
  New Features
  ============
  
  revert --interactive
  --------------------
  
  The revert command now accepts the flag --interactive to allow reverting only
  some of the changes to the specified files.
  
  Rebase with different destination per source revision
  -----------------------------------------------------
  
  Previously, rebase only supports one unique destination. Now "SRC" and
  "ALLSRC" can be used in rebase destination revset to precisely define
  destination per each individual source revision.
  
  For example, the following command could move some orphaned changesets to
  reasonable new places so they become no longer orphaned:
  
  hg rebase   -r 'orphan()-obsolete()'   -d 'max((successors(max(roots(ALLSRC) &
  ::SRC)^)-obsolete())::)'
  
  Accessing hidden changesets
  ---------------------------
  
  Set config option 'experimental.directaccess = True' to access hidden
  changesets from read only commands.
  
  githelp extension
  -----------------
  
  The "githelp" extension provides the "hg githelp" command. This command
  attempts to convert a "git" command to its Mercurial equivalent. The extension
  can be useful to Git users new to Mercurial.
  
  Other Changes
  -------------
  
  * When interactive revert is run against a revision other than the working
    directory parent, the diff shown is the diff to *apply* to the working
    directory, rather than the diff to *discard* from the working copy. This is
    in line with related user experiences with 'git' and appears to be less
    confusing with 'ui.interface=curses'.
  
  * Let 'hg rebase' avoid content-divergence by skipping obsolete changesets
    (and their descendants) when they are present in the rebase set along with
    one of their successors but none of their successors is in destination.
  
  * hgweb now displays phases of non-public changesets
  
  * The "HGPLAINEXCEPT" environment variable can now include "color" to allow
    automatic output colorization in otherwise automated environments.
  
  * A new unamend command in uncommit extension which undoes the effect of the
    amend command by creating a new changeset which was there before amend and
    moving the changes that were amended to the working directory.
  
  * A '--abort' flag to merge command to abort the ongoing merge.
  
  * An experimental flag '--rev' to 'hg branch' which can be used to change
    branch of changesets.
  
  Backwards Compatibility Changes
  ===============================
  
  * "log --follow-first -rREV", which is deprecated, now follows the first
    parent of merge revisions from the specified "REV" just like "log --follow
    -rREV".
  
  * "log --follow -rREV FILE.." now follows file history across copies and
    renames.
  
  Bug Fixes
  =========
  
  Issue 5165
  ----------
  
  Bookmark, whose name is longer than 255, can again be exchanged again between
  4.4+ client and servers.
  
  Performance Improvements
  ========================
  
  * bundle2 read I/O throughput significantly increased.
  
  * Significant memory use reductions when reading from bundle2 bundles.
  
    On the BSD repository, peak RSS during changegroup application decreased by
    ~185 MB from ~752 MB to ~567 MB.
  
  API Changes
  ===========
  
  * bundlerepo.bundlerepository.bundle and
    bundlerepo.bundlerepository.bundlefile are now prefixed with an underscore.
  
  * Rename bundlerepo.bundlerepository.bundlefilespos to _cgfilespos.
  
  * dirstate no longer provides a 'dirs()' method.  To test for the existence of
    a directory in the dirstate, use 'dirstate.hasdir(dirname)'.
  
  * bundle2 parts are no longer seekable by default.
  
  * mapping does not contain all template resources. use context.resource() in
    template functions.
  
  * "text=False|True" option is dropped from the vfs interface because of Python
    3 compatibility issue. Use "util.tonativeeol/fromnativeeol()" to convert EOL
    manually.
  
  * wireproto.streamres.__init__ no longer accepts a "reader" argument. Use the
    "gen" argument instead.
  
  * exchange.getbundlechunks() now returns a 2-tuple instead of just an
    iterator.
