[i3] Add compositor

KDE applications in i3 were showing only "Other..." in default
applications due to missing applications.menu file. Plasma 6 renamed
applications.menu to plasma-applications.menu but KDE components
still look for the old name.

This creates a symlink from the new location to the expected location
using XDG config file management.

Fixes kmail and systemsettings not detecting installed applications.
