feat: upgrade to zfs 2.2+

This changes the ZFS version to 2.2, which as of today is 2.2.2. The
2.2.2 release fixed the file corruption issues which had been present
in 2.2.0. see: https://github.com/openzfs/zfs/releases/tag/zfs-2.2.2

Note that ucore will remain on ZFS 2.2.x until this version field is
updated again after ZFS 2.3 hs proven somewhat stable.

Fixes: #88
