chore(publish): Bump next entries in changelog when releasing

[Lms24]

We recently added changelog entries to the attribute schema and decided to tag yet unreleased changes with "next". This PR now ensures that all next entries are changed to the version to be released via our craft pre-release script. Importantly, this means we also need to regenerate the JS and python code after bumping since the changelog is added to the generated code metadata.

This script also does some cleanup like merging PRs mentioned multiple times. Tested locally and ensured it's idempotent. This should be good enough for releasing.
