Support commit refs

[golemiso]

Summary

This PR fixes #1931 by updating the logic for retrieving the tag name from the current commit.
Instead of relying on potentially outdated tag references, the workflow now checks out the action_ref and uses git tag --points-at HEAD to accurately identify the tag associated with the current commit.

Changes

• Checkout the commit using action_ref
• Retrieve the tag name with git tag --points-at HEAD
• Ensure consistent and reliable tag resolution during the workflow run
