hotfix: move intranet DNS override out of GCP build clusters

[deepsm007]

• Allow operator.openshift.io/DNS in the build-clusters Argo CD AppProject so per-cluster openshift-dns/dns.yaml passes cluster-manifest-verifier (synced by appset-cluster-build).

Summary by CodeRabbit

This PR limits the rh-intranet DNS override to AWS build clusters.

• Stores the DNS configuration in build10 and shares it with selected AWS clusters through symlinks.
• Removes the override from shared configuration, build01, and GCP build clusters.
• Updates the dpu-operator e2e nameserver helper to use the new build10 path.
• Allows the build-clusters Argo CD AppProject to manage operator.openshift.io/DNS resources.

Walkthrough

The change moves selected build-cluster DNS references to build10, permits Argo CD to manage the DNS resource, and updates the DPU operator e2e helper to read the build10 configuration.

Changes

DNS placement and lookup

Layer / File(s)	Summary
DNS configuration and Argo CD access clusters/build-clusters/build03/openshift-dns/dns.yaml, clusters/build-clusters/build05/openshift-dns/dns.yaml, clusters/build-clusters/build06/openshift-dns/dns.yaml, clusters/build-clusters/build07/openshift-dns/dns.yaml, clusters/build-clusters/build09/openshift-dns/dns.yaml, clusters/build-clusters/build11/openshift-dns/dns.yaml, clusters/build-clusters/build12/openshift-dns/dns.yaml, clusters/gitops/apps/appproject-build-clusters.yaml	The seven cluster DNS manifests now link to the build10 DNS manifest. The AppProject whitelist now includes operator.openshift.io/DNS.
E2E DNS lookup references ci-operator/step-registry/dpu-operator/e2e-tests-workflow/tests/dpu-operator-e2e-tests-workflow-tests-commands.sh	The get_nameservers URLs and the resolve_name comment now reference the build10 DNS configuration.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix · Severity of issue fixed: Low

Merge Risk: 🔵 Low · up to 85ca2

The change is mergeable with a small documentation correction: the DNS helper comment should link to the same main branch used at runtime.

Use main in the documentation comment.

Line 73 fetches the DNS manifest from refs/heads/main, but this comment still points to blob/master. Change master to main so the documented source matches the runtime source.
