rgw: radosgw-admin man page doesn't contain the "orphans" commands
The orphans commands were added to
radosgw-admin --help" in #14516. We should add them to the man page as well.
doc: add orphans commands to radosgw-admin(8)
The --help text was added in 105a76bf542e05b739d5a03ca8ae55432350f107.
Add the corresponding entries to the man page.
