4. - [x] Mandatory for GA content:

• [x] Add steps, the diff, known issue, and/or other important conceptual information in the
  following space:
  • The `objectSelector` is added to allow a `ConfigurationPolicy` to filter and iterate over an unnamed `objectDefinition`. This also now allows such a policy to be enforced.
  • The `.ObjectName` context variable is added to allow the name of the object to be used in Go templates.
  • The `skipObject` Go template function is added to allow conditionally skipping an object using Go templates.
• [x] Add Required access level _(example, _Cluster Administrator) for the user to complete the task: Hub cluster Policy manager
• [x] Add verification at the end of the task, how does the user verify success (a command to run or a result to see?)
• [x] Dev story:
  • This issue covers the remainder of the stories in the ACM-15388 Epic:
  • `objectSelector`: ACM-15389
  • `.ObjectName` context variable: ACM-15809
  • `skipObject` Go template function: ACM-15937
