stone-stage-p01: remove member operator resources (#7488)

Member operator has been removed from the toolchain-member-operator
namespace, so we can clean up all the remaining resources.  Remove all
resources from the toolchain-member-operator-stone-stage-p01 application
(except the namespace, since argocd requires at least one resource).
