Change ordering of account types in Settings | Online Accounts

Currently (Dogwood), the initial list of providers consists of Nextcloud and seven of the internet's worst offenders. I realize this is inherited from desktop Gnome and that it has some merit for people using these services, when migrating from iOS/Android to the Librem 5. However, it doesn't reflect the core values of the phone.

Please, consider putting open services (like Nextcloud, XMPP, Matrix, IMAP...) on top and moving Google, Facebook et.al to the more options "..." section.

Bonus points for adding a warning mark (yellow triangle or similar) to the bad guys.
