Add optional "same branch only" input

[gavinsharp]

This adds a same-branch-only input which can be set to false if you want to wait on pending runs regardless of which branch they're from.

I was trying to use this action to prevent simultaneous deploys, but realized it would only work to prevent deploys from the same branch. In our setup all non-main branches deploy to the same environment, so I need to wait on any pending run, even if it is from a different branch.

(Even more ideal would be a way to say "wait for all main or non-main branches, depending on whether this is a run from main or non-main", but that seemed too complex and also maybe too unique to our particular deploy setup to be worth supporting.)

This parameter defaults to true to preserve existing behaviour.

It looks like passing undefined as the branch param to OctokitGitHub.runs is not behaving the way I would expect (finds no runs rather than finds all runs). Let me find a way to fix that.

Fixed in 53c876b.

I was trying to figure out a way to write a test to capture the actual functionality better, but since the underlying behaviour that matters (filtering by branch) lives in Octokit, testing a mocked Octokit didn't seem that useful.

I'm sorry. I've let this one go. If you'd still like this functionality can you rebase with latest version of the code? I can commit to taking a look this weekend.

No worries. I've merged in master (just required a rebuild for dist/index.js, merged cleanly otherwise)

I lied: trivial fix also needed for the new test (935b7e2)

I'm waiting for this, thanks! <3

This would be a great addon for terraform operations (which relies on shared resources)

I'll update the tag for this today
