Update scalameta to support new given syntax (SIP-64)

[jberkel]

The new given syntax as described in SIP-64 has been released as non-experimental in the Scala 3.6.x series. The default version of scalameta used in pants doesn't support this syntax yet, so you'll get compile errors during the dependency analysis stage (which is also very confusing, since a user might assume it happened during the compilation stage).

This PR updates scalameta to a more recent version which supports this syntax.

Failing test case (without the scalameta update):

pants.engine.process.ProcessExecutionFailure: Process 'Scala source dependency analysis failed.' failed with exit code 899.
stdout:

stderr:
__source_to_analyze/Source.scala:8: error: ; expected but : found
    given intOrder: Ord[Int]:
                            ^

Looks like this is already being addressed in #22767

Yeah, and as I mentioned over there - I'm working on Dependabotting some of it, so the PR might linger.

But thanks for this one! Once we come up with some reasonable approach, we can close both of these PRs at the same time.

No worries, I'm manually overriding the dependencies for now in pants.toml. The test might be useful to pick from this PR. Is it worth having dependabot support for this? I don't think there'll be many updates, only for major Scala syntax changes, which don't occur that often.

Thanks for the contribution. We've just branched for 2.31.x, so merging this pull request now will come out in 2.32.x, please move the release notes updates to docs/notes/2.32.x.md if that's appropriate.
