There is no reason to disallow exposed sctp ports at all. As root we can
publish them find and as rootless it should error later anyway.
And for the case mentioned in the issue it doesn't make sense as the
port is not even published thus it is just part of the metadata which is
totally in all cases.
Fixes#23911
