gitlab-ci: make metadata_v0 test work even when tags are missing

This uses the commit ID of the release tags, rather than the release tag
itself so that contributor forks do not need to include the tags in them
for this test to work.

The COMMIT_ID should be bumped after each release, so that the list of sed
hacks needed does not continuously grow.
