OCP < 4.11: Dex pod in less privileged namespace fails to come up, citing containerconfigerror

Reliably (3 times now), using the following repo and branch:

https://github.com/mhjacks/multicloud-gitops/tree/repro-dex-failure

(Installing the pattern, by running `make install` on a fresh cluster)

The dex pod in the multicloud-gitops-hub namespace will fail to come up:

container has runAsNonRoot and image will run as root (pod: "hub-gitops-dex-server-68bfc4bf9-656k7_multicloud-gitops-hub(ea242591-5b38-4c8b-b4c5-d4dd04144ebf)", container: dex)

The same manifests will apply without error on Gitops 1.5.

The cluster-scoped installation dex pod in openshift-gitops comes up without error and works for Oauth with the default cluster-admin account.

Cluster-scoped dex pod securityContext:

```

securityContext:
      allowPrivilegeEscalation: false
      capabilities:
        drop:
        - ALL
        - KILL
        - MKNOD
        - SETGID
        - SETUID
      runAsNonRoot: true
      runAsUser: 1000650000

```

non-cluster-scoped securityContext:

```

securityContext:
      allowPrivilegeEscalation: false
      capabilities:
        drop:
        - ALL
        - MKNOD
      runAsNonRoot: true
