Wrong default argument to ls (detail=False)

https://github.com/fsspec/sshfs/blob/15aac74de1d2e1c28376e70211397a8533318977/sshfs/spec.py#L210C31-L210C43

I think it is unexpected behavior for the default argument to be different form the filesystem [abstract class specification](https://filesystem-spec.readthedocs.io/en/latest/api.html#fsspec.archive.AbstractArchiveFileSystem.ls).
