Fixes an issue introduced in [1] where gtk4 apps would print the
following warning:
> Error setting gtk-interface-color-scheme in
> /home/mithic/.config/gtk-4.0/settings.ini: Key file contains key
> “gtk-interface-color-scheme” which has a value that cannot be
> interpreted.
The value should be set to the nickname ("light" or "dark" in this
case), rather than the actual numerical value of the enum. This lookup
happens at [2].
These nicknames appear to be undocumented and automatically generated at
compile time, but in general they appear to follow the pattern where an
enum value FOO_BAR_BAZ_QUUX of the enum FOO_BAR has nickname "baz-quux".
Regardless, they can be looked up in the generated file
gtktypebuiltins.c (it unfortunately appears that nix only keeps
gtktypebuiltins.h, which does not contain the nicknames).
