Description of Changes

1. Add /run/current-system/sw/bin to nwg-drawer PATH:

   • This change allows nwg-drawer to properly run applications via their .desktop files even if the full path to the binary is not provided in Exec=
   • With this change, if a particular package, added via environment.systemPackages has its own .desktop entry, nwg-drawer will be able to launch it without issues.
   • The reason this change is needed is because we start nwg-drawer as a user service. By default, it seems to inherit the service manager's PATH, which does not include /run/current-system/sw/bin.

2. Minor adjustment to default gtk settings files, removing unsupported properties

Test Steps To Verify:

Testing is not necessary, as this change should not affect existing functionality and it doesn't add anything new yet.
That being said, a sanity check can be performed:

1. Find the process ID of nwg-drawer via ps aux | grep nwg-drawer
2. Check the PATH env var for the nwg-drawer process: cat /proc/[PROC-ID-HERE]/environ | tr '\0' '\n' | grep PATH --color=auto
3. PATH should contain /run/current-system/sw/bin
