[PRQ#50623] Merge Request for lightdm-gtk-greeter-devel

MarsSeed [1] filed a request to merge lightdm-gtk-greeter-devel [2] into lightdm-gtk-greeter-git [3]: The devel package was made originally for the Launchpad prerelease versions. Now only the git package makes sense, as upstream hasn't released any tags, stable or preview, since 2020. But the git master branch is still receiving updates and maintenance commits.
