packaging: update keyring on Windows to avoid spurious stacktraces

When challenged for a network password, this would spew on Windows before it
actually used the stored password:

```

We're kinda threading a needle here because the next version of `keyring`
(currently at 23.7.0) requires `importlib-metadata` 3.6+, which PyOxidizer 0.22
doesn't support[1].

 * revlog: reorder p1 and p2 when p1 is null and p2 is not while respecting issue6528
 * rhg: add support for ignoring all extensions
 * completion: install completers to conventional locations
 * revert: ask user to confirm before tracking new file when interactive
 * Rust implementation now uses the new dirstate API
 * sslutil: be less strict about which ciphers are allowed when using --insecure
 * sslutil: support TLSV1_ALERT_PROTOCOL_VERSION reason code
 * absorb: make `--edit-lines` imply `--apply-changes`
