ogabrielluiz 79c3cb3933 fix(ci): create GitHub release on the source tag, not main HEAD
The create_release job tagged the release with determine-main-version's
output, which strips the v prefix, and passed no commit. ncipollo then
created a bare vless tag (e.g. 1.10.0) at the default branch HEAD instead
of the validated source tag (v1.10.0). GitHub generateReleaseNotes
compared that bare tag against the previous bare tag, so the changelog
only captured PRs merged directly to main and missed everything that
shipped through the release branch.

Tag the release on inputs.release_tag and pin the commit to it. This is
the same vless-duplicate-tag failure the validate-tag-format job already
warns about.
