SelinuxProfiles do not inherit the custom SelinuxProfiles from the same namespace.

OCP 4.12 + SPO 0.7.1

>> Yes reproducible

1.Create a selinuxProfile in any namespace as per the attachment cdmrf-common
2. Inherit the cdmrf-common SelinuxProfile to other SelinuxProfile cdmrf-hook in the same namespace
~~~
  inherit:
  - kind: SelinuxProfile
    name: cdmrf-common
~~~
3. It will go into the Error state as follows:
~~~
  "status": {
    "conditions": [
      {
        "lastTransitionTime": "2023-08-01T16:00:27Z",
        "reason": "Unavailable",
        "status": "False",
        "type": "Ready"
      }
    ],
    "status": "Error",
    "usage": "cdmrf-hooks_openshift-security-profiles.process"
  }
}
~~~
4. Also found the following error in the events:
~~~
Profile failed validation on ip-10-0-159-170.ap-south-1.compute.internal: SelinuxProfile/cdmrf-common: unknown inherit kind for entry
~~~

SelinuxProfile cdmrf-common is not inherited with cdmrf-hook SelinuxProfile created in the same namespace

During inheritance, there should not be any errors.

Found SelinuxPolicy kind in the code[1] which should be fixed. We have tested with SelinuxPolicy kind but not worked. 
~~~
Error "Unsupported value: "SelinuxPolicy": supported values: "System", "SelinuxProfile"" for field "spec.inherit[0].kind".
~~~

It would be also fixed in the document[1]
