fix: Add missing release_id to shared logging extra dict

The shared logging extra dict was missing the release_id field, which was
previously explicitly included in the fetch_commits.duplicate log. Adding
it to the shared extra dict ensures all log statements (fetch_commits.start,
fetch_commits.duplicate, fetch_commits.complete, and loop logs) include
the release_id for better debuggability.
