doc/cephfs: s/subvolumegroups/subvolume groups

Use the term "subvolume groups" instead of "subvolumegroups" where the
term appears in plain English. The string "subvolumegroups" is correct
in commands, and remains unchanged.

Also add formatting to command output, to make clearer that the output
is indeed output.
