feat: allow skip cancel if named job in progress

[mrbrannan]

👋

I have a use case where if a named job is currently running the workflow should not be cancelled (deploying to S3). I figured I would create a PR in case anyone else sees value in the functionality.

Also open to any input, first PR for a github action.

Awesome work btw!

This is not a democracy really, but I do want to register in this as well - this happens to me in one repo with one specific job and right now I'm just careful with what I run at the same time :-)

Thanks for the PR!

If this gets a few upvotes and others want it, we can merge it.

I'll review soon 👍

This would be really great to have!

This would be amazing to have, I was looking to implement exactly this.
