Update Apparmor configuration and related docs

[mythi]

Describe the bug
QAT plugin Apparmor settings are outdated

To Reproduce
See intel-qat-plugin.yaml.

Expected behavior
Apparmor is GA starting k8s v1.30. The settings and documentation must be updated.

Screenshots
N/A

System (please complete the following information):

• Kubernetes v1.30+

Additional context
Ubuntu and SUSE based distros have Apparmor enabled and that blocks certain QAT plugin functions. In particular, when the plugin tries to write QAT VF IDs to vfio-pci driver. Other plugins are not impacted.

Adding

securityContext:
  appArmorProfile:
    type: unconfined

to intel-qat-plugin.yaml is easy but then we loose configurability which we had with the annotation but is that needed? It is possible to configure nodes so that unconfined is not needed so likely some configurability is useful.
