Issue packaging theme as a flake

Hi! I'm the guy that said they would like to try packing your theme as a flake on reddit. This makes it easier for nixos users to use the theme.

Unfortunately, I've hit a roadblock. The flake builds successfully and installs the theme directory into the Nix store, but when I try to use the theme, SDDM refuses to load it and throws an error like:

SDMM Error

Fallback to embedded theme

I've verified that:

• The theme directory is complete(no missing files).
• SDDM config is set correctly.

SDDM config

[General]
DefaultSession=
DisplayServer=x11
GreeterEnvironment=QML2_IMPORT_PATH=/run/current-system/sw/share/sddm/themes/silent/components/,QT_IM_MODULE=qtvirtualkeyboard
HaltCommand=/run/current-system/systemd/bin/systemctl poweroff
InputMethod=qtvirtualkeyboard
Numlock=none
RebootCommand=/run/current-system/systemd/bin/systemctl reboot

[Theme]
Current=silent
FacesDir=/run/current-system/sw/share/sddm/faces
ThemeDir=/run/current-system/sw/share/sddm/themes

The sddm error is pretty cryptic to me. I have no idea what it mean. I'm wondering if you know whats going on.
