refactor(tests): replace HashSet.Of() and HashMap.Of() with inherited static methods from its interfaces during upgrade to spring boot 2.7.x

While upgrading spring boot 2.7.18, encounter below errors during test compilation of fiat-roles module:
```
No signature of method: static java.util.HashSet.of() is applicable for argument types: (com.netflix.spinnaker.fiat.model.resources.Role) values: [Role(resourceType=role, name=role1, source=null)]
Possible solutions: is(java.lang.Object), max(), any(), sort(), sum(), min()

```
```
No signature of method: static java.util.HashMap.of() is applicable for argument types: (String, String, String, String) values: [foo, bar, xyz, pqr]
Possible solutions: any(), sort(), notify(), wait(), size(), clone()

```
Spring boot 2.7.18 brings groovy 3.0.19 as transitive dependency. The root cause of the issue is a breaking change introduced from groovy 3.0.18 onwards, that allows a Java class to inherit static methods from its interface. To fix these issues replacing the HashSet.Of() and HashMap.Of() with Set.Of() and Map.Of().
