PR_SET_CHILD_SUBREAPER is unavailable on this platform

I have a local k3s Kubernetes created by [Rancher Desktop](https://rancherdesktop.io/) on MacBook Pro with M1 chip.

I try to install spark-on-k8s-operator by

```sh
helm repo add spark-operator https://googlecloudplatform.github.io/spark-on-k8s-operator
helm install spark spark-operator/spark-operator --namespace spark-operator --create-namespace
```

However, I got the error for the pod `spark-spark-operator-6964986646-5vctk`:

```sh
++ id -u

[FATAL tini (1)] PR_SET_CHILD_SUBREAPER is unavailable on this platform. Are you using Linux >= 3.4?
```

Any idea? Thanks! 😃

Start by reproducing the Helm installation on the reported Rancher Desktop k3s cluster on an M1 Mac, then inspect the failing pod logs and the reported tini error. The issue does not name a source file or test; done would mean establishing whether the spark-operator deployment can run on this platform or documenting the required platform limitation.
