compat: drop advertising of unsupported experimental bundle2 part

The support for this part was dropped long ago in 74bc8a0c2c02. But we forgot
to remove it from the 'simple4server' extension.

Test script based on sharing.rst: ensure that all scenarios in that
document work as advertised.

Setting things up

To start things off, let's make one public, immutable changeset::

  $ cd test-repo
  $ echo 'my new project' > file1
  $ hg add file1
  $ hg commit -m'create new project'
  $ hg push
  pushing to $TESTTMP/public (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files

and pull that into the development repository::

  $ cd ../dev-repo
  $ hg pull -u
  pulling from $TESTTMP/test-repo (glob)
  requesting all changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

Let's commit a preliminary change and push it to ``test-repo`` for
testing. ::

  $ echo 'fix fix fix' > file1
  $ hg commit -m'prelim change'
  $ hg push -q ../test-repo

  $ hg shortlog -G

  o  0:0dc9c9f6ab91  public  create new project
  
Now let's switch to test-repo to test our change and amend::
  $ cd ../test-repo
  $ hg update -q
  $ echo 'Fix fix fix.' > file1
  $ hg amend -m'fix bug 37'
