Append noctalia.css import to the end of gtk-4.0/gtk.css instead of overwriting it

Pull Request

Motivation

As it currently stands, the GTK color scheme template overwrites the contents of ~/.config/gtk-4.0/gtk.css with @import url("noctalia.css");. This has the adverse effect of wiping any user-made modifications to the file.

This request addresses the issue by having the noctalia.css import appended to the end of gtk.css, rather than overwriting it. This new behavior is similar to that of the niri template. If the import is already present, nothing is written, and if the file doesn't exist, it is made with the import as per the previous functionality.

Heyo @finsofblueimnotyou , we split gtk into gtk3 & gtk4 not too long ago, if you'd like to manage that, I'd be all for merging it.
