feat(templates): add glow, shadow, and groupbar text colors to hyprland.lua

[yipfluoric]

Summary

This adds the colors for Hyprland's glow, and shadow, as well as the groupbar text to the hyprland.lua template.

Motivation

Glow, and shadow is mostly just making it consistent with other settings/compositor templates

The groupbar text however is due to readability issues. The default setting conflicts with lighter backgrounds and dark themes, as Hyprland does not use backgrounds for it's groupbar text.

Additional Notes

This could be added to hyprland.conf as well, but not really recommended as the next version will not have support for it

There is also no locked color setting for the glow effect currently, so it will look weird with borders.

Would need a proper background for group headers, this wont work with all wallpapers.

[yipfluoric]

Changed the glow color as it looks far more consistent between locked and unlocked groups. Honestly fits better with Noctalia's defaults imo.

[ItsLemmy]

Can you check how does that look now with my latest commit.

[yipfluoric]

This does a really good job at fixing that issue. There probably should be settings in the docs, to make groupbar look nicer with noctalia. But other than that this works really well!
