Superseded by #368, which took all ten open Dependabot bumps as one batch (5f0b465, now on main). The four OpenTelemetry crates only resolve together, and utoipa 6 needed a source change, so they could not land one at a time.

[dependabot]

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.
