Bump nextcloud to version 22 in 0.8.7
HomeLabOS bumped version number of nextcloud 4d397c86 for the 0.8.5. Since that patch was created, NextCloud has released both versions 22(July 6 2021) and 23(November 30 2021). Since Nextcloud does not support jumping over major revisions. I propose bumping to nextcloud 22 in 0.8.7 and nextcloud 23 in a later version. By waiting a few months till bumping the version number, or being one major revision behind, we can make sure that the version we default to is well tested and HomelabOS users aren't subjected to unstable software.
