…tcd-io#16912

KubeconNA 2023 Contribfest issue etcd-io#16893 . Recently in etcd-io#16801 we introduced on demand github actions runners for the arm64 platform. Having on demand runner infrastructure in place means we should now have enough capacity to begin running arm64 tests for every pull request. Currently we have:
.github/workflows/e2e-arm64-template.yaml - Shared template
.github/workflows/e2e-arm64-nightly.yaml - Runs template against both
release-3.5 and main branches nightly. Moving forward we can just rename
.github/workflows/e2e-arm64-template.yaml to
.github/workflows/e2e-arm64.yaml and delete the other file. We can then
just make the template file a standard workflow that will run on pull
request.
