Added a new config option programs.firefox.profiles.<name>.storeId.
Setting this option now writes the StoreID both to the profiles.ini
and to the settings."toolkit.profiles.storeID" of the profile.
Firefox has two different profile implementations;
- the old one that home-manager module can declare
- the new "Selectable Profile Service" introduced in 150
The new profiles are managed in a runtime db, and reads from profiles.ini
Migration without database operations is not possible right now,
but when it becomes available, this option will stop home-manager from
clobbering the linked storeIDs.
