Fix os_keystone_endpoint endpoint_interface docs (#62283)

The os_keystone_endpoint module has two interface arguments -
'interface' for authentication, and 'endpoint_interface' for the
endpoint being registered. Currently the module documentation only
covers 'interface', when in fact it should cover 'endpoint_interface'
and pick up 'interface' from the standard OpenStack module parameter
documentation.
