fix(ci): remove act tests for release and release-preview workflows

act does not propagate with: inputs into nested workflow_call, causing
false failures. release-preview also uses curl which is absent from the
micro image. Both are validated by actionlint; end-to-end testing
happens in the per-repo migration PRs.
