THe list of breaking changes is also somewhat long and distinguished 🤔

I don't know when we turned on the feature to auto detect API changes, but I suspect we're getting better at reporting.

## Which issue does this PR close?

- Part of the 55.0.0 release:
apache#22393

## Rationale for this change

Now that DataFusion 55.0.0 has been released from `branch-55`, bring the
version bump and release notes back to `main` so the changelog and
version numbers are consistent.

## What changes are included in this PR?

Cherry-picks the release commits from `branch-55`:

- apache#24292 (version number,
changelog)
- apache#24295 (additional version
references)
- apache#24314 (changelog update)
- apache#24385 (changelog update)

## Are these changes tested?

By CI (version/docs/changelog changes only)

## Are there any user-facing changes?

Version on `main` is now `55.0.0` and `dev/changelog/55.0.0.md` is added
