language selection popup
WIP: because it's not over yet.
WIP because needs !223 (merged)
Strongly recommends !186 (merged) or it will be hard to see and test changes.
Needs https://source.puri.sm/Purism/Systems-Tasks/issues/451 for pipelines.
Left to do:
-
specify Debian deps -
position the popover -
clean up commits -
translate and sort language names
