Updates the requirements on rustls to permit the latest version.

Release notes

Sourced from rustls's releases.

0.22.2

• Support NISTP521-SHA512 signatures (both for verification and signing), when used with the aws-lc-rs provider (#1706).

Dependabot tried to update this pull request, but something went wrong. We're looking into it, but in the meantime you can retry the update by commenting @dependabot rebase.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
