Migrate release.yml to GitLab CI (releases)

To be able to release the GitLab CLI, we need to create jobs to build and release the CLI tool.

The GitHub actions for this process are in:

https://gitlab.com/gitlab-org/cli/-/blob/main/.github/workflows/release.yml

Use go-releaser https://goreleaser.com/ci/gitlab/

Current accounts that we might not be able to access/support
