btrfs-progs: docs: update feature status

Add some missing entries. Changes to supported levels:

- increase to 6.8 from 6.7 where applicable, there were fixes to squota
  and temp-fsid

- raid-stripe-tree declares support from 6.7, however this is still
  behind CONFIG_BTRFS_DEBUG option in kernel, there are some bugs
  and the known lack of RAID56 support

[ci skip]
