feat(cli-aliases): update aliases in GitHub and GitLab CLI

To ease migration to GitLab and the official CLI itseld,
I made 'gh mr' as alias to 'gh pr'.

Notes:
* `glab` is now officially adopted by GitLab team since 2022-12-07!
  See https://about.gitlab.com/blog/2022/12/07/introducing-the-gitlab-cli/
  and https://about.gitlab.com/releases/2022/12/22/gitlab-15-7-released/
  for all the details.
