Gnome 44 release

Thanks to @hrqmonteiro (see #56) for working on the first upgrade to gnome 44.

Big thanks to @brenard for fixing a bunch of issues and updating the settings window (see #62). This should also work on gnome 43 but it hasn't been tested extensively.

July 2023: Made some changes to comply with extensions.gnome.org regulations and discard unused variables.

October 2023: Thanks to @MexHigh we now support scenes and scripts!
