Replace t2a-standard-4 with n4a-standard-4 in multiarch-tuning-operator configs

Updates COMPUTE_NODE_TYPE from t2a-standard-4 to n4a-standard-4 for ARM64 test configurations across openshift, openshift-priv, and outrigger-project multiarch-tuning-operator variants.

t2a-standard-4 is old and starting to be phased out.

level=error msg=A t2a-standard-4 VM instance is currently unavailable in the us-central1-a zone. Consider trying your request in the us-central1-f, us-central1-b zone(s), which currently has capacity to accommodate your request. Alternatively, you can try your request again with a different VM hardware configuration or at a later time. For more information, see the troubleshooting documentation.

Walkthrough

This PR updates compute node types used in CI end-to-end test configurations for the multiarch-tuning-operator. The COMPUTE_NODE_TYPE environment variable is changed from t2a-standard-4 to n4a-standard-4 across 24 CI operator YAML configuration files spanning three organization/repository combinations and multiple OpenShift versions and operator release versions.

Stable And Deterministic Test Names ✅ Passed Check not applicable. PR modifies only CI config YAML files, not Ginkgo test source code. No test names changed.
Test Structure And Quality ✅ Passed The custom check for Ginkgo test code is not applicable. The PR only modifies 26 YAML CI configuration files, updating compute node types. No test code or Go files are present.
Microshift Test Compatibility ✅ Passed This PR only modifies CI configuration YAML files, updating COMPUTE_NODE_TYPE values. No new Ginkgo e2e test code is added. The custom check applies only to new tests, so it is not applicable.
Single Node Openshift (Sno) Test Compatibility ✅ Passed This PR modifies only CI configuration files (YAML), not Ginkgo test code. The custom check applies only to new e2e tests; not applicable here.
Topology-Aware Scheduling Compatibility ✅ Passed Changes are CI-operator configuration files only, not deployment manifests, operator code, or controllers. No scheduling constraints introduced. Check not applicable.
Ote Binary Stdout Contract ✅ Passed PR contains only CI configuration file changes (YAML), no source code modifications. OTE Binary Stdout Contract check applies to source code process-level stdout emissions, not config files.
Ipv6 And Disconnected Network Test Compatibility ✅ Passed This PR does not add new Ginkgo e2e tests. It only updates CI operator YAML configuration files to change compute node types. The custom check applies only to new test code, so it is not applicable.
