DOC: management: apply the "show stat" modifiers to "show stat", not "show info"

By mistake I added the "up" then "maint" output modifiers to the "show info"
block instead of the "show stat" one in the two previous commits 65141ffc4
("MINOR: stats: support the "up" output modifier for "show stat"") and
3e3203670 ("MINOR: stats: also support a "no-maint" show stat modifier").

No backport is needed.
