Tag main as 0.31 canary (#7332)

We are updating our git worklow.

Case 1: **URGENT / PATCH**
If you want to include something URGENT that cannot wait for the next
release, you'll need to:
- create a PR from the latest patch (right now v0.30.1)
- create a new patch tag from this PR (would be v0.30.2 right now)
- merge this PR in main so it's in 0.31 too

Case 2: **REGULAR**
- Open a PR from main and merge it into main

I'm tagging main as v0.31.canary to make it clear!
