audio/spotify-qt: update to 3.3

Fixes:
-Fixed not sorting by track number correctly in some cases (#29).
-Fixed showing "View artist" from tracks in artist view, which opened an empty
artist.
-Fixed not saving settings for changelog and playback order properly.
-Fixed some possible issues with media controller in snap (#38).
-Fixed copying an album link to clipboard, copying an invalid link.
-Fixed failing to refresh playlist, showing an empty list.

Changes:
-Added setting to use relative dates (... ago instead of exact date)
(enabled by default).
-Improved Qt 6 support (compile with -DUSE_QT6=ON to link against Qt 6).
-Added a new --reset-credentials parameter to reset Spotify credentials (#39).
-Renamed library items to be make more sense (still in the same order).
-Hovering over a year for an album in artist view now shows the full release
date.
-Removed "single click to play tracks" settings, as it's now automatic depending
on system setting (#40, #41).
-Space can now be used to play/pause while the application has focus.
-Added ability to search for a single item by pasting the URL or ID of the item.
