[PRQ#59773] Merge Request for drush-launcher-git

MarsSeed [1] filed a request to merge drush-launcher-git [2] into drush-launcher [3]: Upstream repository is now EOL and read-only (archived). [a] AUR/drush-launcher has recently been updated by its owner and it works fine as of now. It has an active maintainer. That package builds from the exact same code version as what is offered by the frozen master branch. Therefore I see no point in keeping the git build. I chose to request a merge to migrate most importantly the user notification subscriptions, as well as the comments.
