Scope the exemptions to NicClusterPolicy resources.

TestComponentManifestImagesAreDigestPinned checks the global imageDigestExemptions map for every image in every component manifest. The four current references occur only in nic-cluster-policy-oke-l40s.yaml, but another resource can reuse one of these tags and bypass the digest check. Scope each exemption by manifest or resource context.

TestComponentManifestImagesAreDigestPinned and the imageDigestExemptions
handling so these four image-tag exemptions apply only to the NicClusterPolicy
resource in nic-cluster-policy-oke-l40s.yaml, rather than globally by image
string. Preserve digest enforcement when any of these images appears in another
manifest or resource.
