Failed to create pod rce-postgres-check

### Helm Chart Version

airbyte-2.0.19

### What step the error happened?

1) Create new Postgres source and click "Set up source"

### Relevant information

Airbyte is trying to create some pod during the CHECKING process of a new Postgres source, but it fails with a completely uninformative error. I have no idea what this pod is, as I've never seen it before. My RBAC looks like this:

```hcl
resource "kubernetes_role_v1" "airbyte_admin" {
provider = kubernetes

metadata {
name = "airbyte-admin"
namespace = kubernetes_namespace_v1.airbyte.metadata[0].name
}
rule {
api_groups = [""]
resources = ["configmaps", "endpoints", "pods", "pods/log", "pods/exec", "pods/attach", "pods/status", "secrets"]
verbs = ["get", "list", "watch", "create", "update", "patch", "delete"]
}
rule {
api_groups = [""]
resources = ["serviceaccounts"]
verbs = ["get", "list", "watch", "use"]
}
rule {
api_groups = ["batch"]
resources = ["jobs"]
verbs = ["get", "list", "watch", "create", "update", "patch", "delete"]
}
}
```

It seems like it has all the permissions to create a pod, but that doesn't help. Initially, I thought the issue was that the pod is trying to be created in the spot-arm64 Karpenter pool (my default pool), but all Airbyte components have nodeSelector and affinity assigned. I don't know if airbyte/workload-init-container:2.0.1 copies the selector settings to the new pod?
