authelia: Use ConfigMap name suffix hash

Without `disableNameSuffixHash` enabled, Kustomize will create a unique
ConfigMap any time the contents of source file change.  It will also
update any Deployment, StatefulSet, etc resources to point to the new
ConfigMap.  This has the effect of restarting any pods that refer to the
ConfigMap whenever its contents change.

I had avoided using this initially because Kustomize does *not* delete
previous ConfigMap resources whenever it creates a new one.  Now that we
have Argo CD, though, this is not an issue, as it will clean up the old
resources whenever it synchronizes.
