Add support for `pull_request` events about lint-action

[samuelmeuli]

The problem is that the action is executed on the pull_request event, which it doesn't support yet (only the push event, which lets the action easily determine which commit needs to be annotated).

I'm planning to fix this though :)

Ah, that makes sense. It should fail the step regardless though, no? Or maybe just explode if ran on an unsupported event altogether

Yeah, I expected this to be the current behavior, but it looks like I removed the check at some point 😅 I'll add it back as a temporary solution and will think about how the pull_request event could be supported.

Released in v0.6.0
