GH-50293: [CI] Run check-labels for all triggers to avoid cancelling further steps and add tag to set_enabled

[raulcd]

Rationale for this change

Currently when check-labels is not a pull_request even the following steps are cancelled. Also we don't enable tags execution which is required for releases.

What changes are included in this PR?

Run check-labels for the specified events and enable jobs for tags.

Are these changes tested?

I've tested on my fork by pushing to main and creating tags, more details on the comment on the PR.

Are there any user-facing changes?

No

I've tested a couple of things on my fork. I've merged the commits on this branches individually and have created a tag on my fork to trigger the jobs.
With the first commit the job was still skipped due to the cancellation propagation on check-labels.

With the second commit the jobs were run:
