chore: refactor rbac.test.ts

[schaeferka]

Describe what should be investigated or refactored

The CapabilityExport[] objects in rbac.test.ts seemsto be re-used by a couple of tests. To be more direct about which keys we are toggling for particular test cases, maybe we should have some sort of generator or a defaultCapabilityExport that we use as a starting point. Then, in each test case, the "Arrange" step involves setting the key(s) that are relevant to the particular test case.

The same idea goes for a lot of the "expected" JSON data
