App list view: filter by supported Nextcloud version

[BernhardPosselt]

ATM you can filter by "featured" and "my apps". It would also be interesting if you could filter by apps that run on a specific nextcloud version. The default should be "All" then Nextcloud versions should be listed in reverse order (11, 10, 9)

Because the filter and sort row is becoming a bit overcrowded, everything that has to do with filtering should be moved to a second row
