[PRQ#57628] Deletion Request for pantheon-dock-instctl-git

MarsSeed [1] filed a deletion request for pantheon-dock-instctl-git [2]: Upstream has rejected PR#73 that is used as a patch here. [a] This package builds from the master branch, but that is obsolete and abandoned. The new default branch is 'main', and the patch used here does not apply to that.
