Rename Helm repository to avoid naming collision

Rename the Helm repository to avoid using the same name used by other
applications in the kube-system namespace.

This fixes a bug where HelmRepository objects belonging to multiple
apps were being removed from the cluster when running "system
application-remove".

Test Plan:
PASS: build-pkgs && build-image
PASS: AIO-SX fresh install
PASS: upload/apply/update/remove/delete app

Partial-bug: 2083985

Depends-on: https://review.opendev.org/c/starlingx/config/+/932120
