[PRQ#61829] Deletion Request for pulsemixer-git

MarsSeed [1] filed a deletion request for pulsemixer-git [2]: Abandoned git package from 2018. Does not align to Python and PulseAudio packaging requirements. GitHub source URL is broken since 2022-03. Seems not useful to keep. As upstream maintenance stopped 4 years ago. [a] The Arch extra repo carries the latest stable release.
