Show "target_project_id" attribute properly for network rbac object

According to the code in SDK:
https://github.com/openstack/python-openstacksdk/blob/master/openstack/network/v2/rbac_policy.py#L34
we can see the conlumn of "target_tenant" should be
"targer_project_id" but not "target_project". It is
the reason why could not show the "target_project"
in OSC, so this patch fix it.

Before this change:
(openstack) network rbac show b74fd644-e057-4d44-8ae1-7ca9967ea1e1
