Link pushed tags to tag pages instead of releases

The PR comment builds tag links as .../releases/tag/${tag}, but in the workflows I inspected this pipeline only creates and pushes Git tags (no GitHub Release creation step). In that setup, releases/tag/... URLs can point to missing release pages, so the “Released in” links in the comment break for contributors. Point to tag URLs (for example /tree/${tag} or /tags) or create releases before using release URLs.

Useful? React with 👍 / 👎.
