[FEATURE REQUEST] Update to Firefox 147

[lukSiBr]

• This request concerns Add Water, the installer app. I'm not requesting a Firefox theme feature.

---

Summary
Update the app to support Firefox 147 new folder locations.

Current Behavior
I can't open the app, and when running flatpak run dev.qwery.AddWater i get the following error:

[ERROR] addwater.apps.firefox.firefox_details — 17:37 || Tried to set app_path to non-existant path. Path given:

[CRITICAL] addwater.apps.firefox.firefox_details — 17:37 || Could not find any valid data paths. App cannot function.

I belive this error is related to firefox's new profile folder locations following xdg specifications on firefox 147 and later.

Additional Context
If you have examples of your request from other apps, feel free to share.

I just realised i was supposed to report this in the theme's repo. My bad

This is definitely my problem since I never added the xdg-base directories. Thanks for letting me know.
