Much like GitHub integration supports fetching Releases and Tags information for repositories (described here: https://docs.port.io/build-your-software-catalog/sync-data-to-catalog/git/github/examples/#map-repositories-repository-releases-and-tags), it can be useful to get this information also from Gitlab.

Releases: https://archives.docs.gitlab.com/17.10/api/releases/

Tags: https://archives.docs.gitlab.com/17.10/api/tags/
