Only error out if the gid exists with a different group name (#59769)

Only error out if the gid exists with a different group name as
otherwise it will error out if the group with this gid already
exists, like on a rerun of the playbook. This fixes a regression
introduced by 4898b0a4a298448677c2aee2a03157ba5b662759.(cherry picked from commit f94772f807)
