Presubmit tests failing

#2364 is failing presubmits because the build client is missing for the default build cluster: ``` status: completionTime: "2024-09-03T23:12:52Z" description: 'Terminal error: nonretryable error: no build client found for cluster "default".' prev_report_states: github-reporter: error startTime: "2024-09-03T23:12:52Z" state: error ``` It is missing because it could not contact the build cluster: ``` [failed to construct manager for cluster default: Get "https://35.233.240.207/api?timeout=32s": dial tcp 35.233.240.207:443: i/o timeout, failed to construct manager for cluster build: Get "https://35.233.240.207/api?timeout=32s": dial tcp 35.233.240.207:443: i/o timeout] ``` This is happening because the build cluster changed IPs. A fix is in progress to update the build cluster kubeconfig: #2365
