Replaced Gnome Tweaks with Gnome Extensions in https://github.com/toozej/ansible/commit/c46db214ada798e6b9be263bd552bda81c4ece48

These two don't work:

• [x] hide top bar #545
• [ ] dash to dock #307

Consider adding:

• [ ] https://extensions.gnome.org/extension/4222/hot-edge/
• [x] https://extensions.gnome.org/extension/3843/just-perfection/

Consider adding once Gnome 40 supported:

• [x] https://extensions.gnome.org/extension/4055/spotify-artwork-fixer/
