- kubeadm: Added better handling of errors during unmount when calling `kubeadm reset`. When failing to unmount directories under `/var/run/kubelet`, kubeadm will now throw an error instead of showing a warning and continuing to clean up said directory. In such situations, it is better for you to inspect the problem and resolve it manually. Then, you can call `kubeadm reset` again to complete the cleanup.

### Bug or Regression

  //
  // A consequence of these requirements is that the delegate futures cannot be stored in
  // final fields.
  //
  // For simplicity the rest of this description will discuss Futures.catching since it is the
  // simplest instance, though very similar descriptions apply to many other classes in this file.
  //

            try (OutputStream out = file.openOutputStream(false)) {
                out.write("Should fail".getBytes("UTF-8"));
            }
        }, "Writing to read-only file should throw exception");

        // Reset to read-write for cleanup
        file.setReadWrite();
        assertTrue(file.canWrite(), "File should be writable after setReadWrite");

- Fixed an incorrect reference to `JoinConfigurationKind` in the error message when no ResetConfiguration is found during `kubeadm reset` with the `--config` flag. ([#132258](https://github.com/kubernetes/kubernetes/pull/132258), [@J3m3](https://github.com/J3m3)) [SIG Cluster Lifecycle]
