Add appropriate permissions for some GraphQL objects

What does this MR do?

This MR has changes extracted from !40088 (merged).

These changes are necessary for !40088 (merged), but are backwards compatible, and can be applied safely here.

This changes a couple of specs to set up the permissions correctly so that when we apply the permissions during resolver specs (implemented in !40088 (merged)) the tests will continue to pass.

Does this MR meet the acceptance criteria?
