Add ability to exclude some types of updates from calculation of last update time

[russellb]

Description:
Configure the types of updates that impact the last updated time.

Justification:
Justification or a use case for your proposal.

My project uses automation of various labels on PRs. If these automated labels are changed, I would like those changes ignored from this action's perspective. One example is a needs-rebase label that gets added if a PR goes into conflict with main. I've noticed that issues are staying open longer as a result.

Related: when a bot adds the needs-rebase label, it also adds a comment. It would be helpful to be able to ignore comments from a set of users (bots) for my use case, as well.

Thanks for the consideration!
