<!--
There's no need to add anything here, but feel free to add a personal message.
Please describe the changes in this PR in the commit message(s) instead, with
each commit representing one logical change. Address code review comments by
rewriting the branch rather than adding commits on top. Use force-push when
pushing the updated branch (`jj git push` does that automatically when you
rewrite a branch).

github: update PR template to explain expectations I think I got the current template from Google's open-sourcing process, but I don't care about most of it (GitHub actions already check that tests pass, for example). Let's instead tell contributors that they don't need to write anything at all there and that they should describe the changes in the commit message(s) instead. 2022-02-27 20:15:39 +00:00			`<!--`
