chore: release 2.4.1

[plamut]

This is a release PR with polished release notes (supersedes #346).

[anguillanneuf]

I think the release notes in the release bot-proposed PR are editable. In Java at least, the edits in the samples directory are not included in the release notes.

[plamut]

@anguillanneuf Are you saying that if one edits the release PR's description, that those changes also get reflected in CHANGELOG.md? That would indeed be quite useful.

[plamut]

Since I might be partially offline tomorrow and won't be able to jump in immediately if anything breaks, I would postpone merging this until Tuesday afternoon or Wednesday morning, unless someone has free cycles to be on alert?

@plamut I believe so. I never touched change.md in the Java repos I know and it has been self-updating based on commit messages.

[plamut]

@anguillanneuf Ah, what I meant was amending the notes if commit messages themselves are incomplete or contain typos (it happens occasionally). One then needs to update CHANGELOG.md manually, or...?

[anguillanneuf]

@plamut Updating the PR description should be enough. We can give it a try to see if it indeed does too. Published release notes can be edited as well in the release notes page if something slips through unintended.

Release is at https://github.com/googleapis/python-pubsub/releases/tag/2.4.1

@busunkim96 Is the release bot stuck? Shouldn't it publish a release to PyPI in 15 minutes or so after tagging a release? :)
