Transition glab supporting accounts to GitLab

As part of &7514 (closed) and transitioning glab to GitLab the following steps need to be completed:

• Identify supporting accounts used for publishing, communication, documentation
• Create new accounts as required
• Transition existing accounts as possible

gitlab-cli@gitlab.com will be the email address used for all new account registrations as required

  • We should look in to redirecting the docs
• brew.sh -
• scoop.sh
• winget
• macports
• twitter? - should we?
  • @phikai removed this from the README, we should shut it down
• gitter? - should we?
