[Release][Packaging] Improve tracking of Linux Packages for Release Candidate

### Describe the enhancement requested

The Linux packages that are released are generated from the tag, example of the jobs here for Arrow 22.0.0 RC1:
- https://github.com/apache/arrow/actions/runs/18655844994

The PR to generate the rest of the binaries and verification tasks also triggers its own Linux packages which are not successful. This is expected and is not a problem, see here:
- https://github.com/apache/arrow/pull/47865

The problem is that sometimes we get some flaky issues on the Packaging jobs and we have to retry those and at the moment there is not an easy way of tracking the jobs on the tag unless we search the workflow manually from the actions tab.

I think it would be beneficial if we could add a comment to the PR with the link to the jobs, something like what I manually did on this comment:
- https://github.com/apache/arrow/pull/47865#issuecomment-3422460764
