Support UPDATE_METHOD=none

[yajo]

If I set up "Require branches to be up to date before merging" in the repo, then this action keeps rebasing my PRs, which would be cool if that could retrigger the checks. However, since that's impossible, this becomes more a problem than a help, as it leaves my PR in a waiting forever status.

Would it be possible to disable this feature? Passing UPDATE_METHOD=none for example.

That's an interesting idea, thx for coming up with it!

You should be able to set UPDATE_LABELS: "disable" (or some other value, basically a label that isn't used), which should disable the update logic

Oh seems legit. Maybe that should be documented...

For me setting this actually disables the automerge functionality too.
