hotfix: Pass .Template to common lib for tpl context

- Updated exporter-controller.yaml to include .Template in the dict
  passed to the bjw-s.common.render.controllers include.
- This is to resolve a 'cannot retrieve Template.Basepath' error
  encountered with the tpl function in older Helm versions (like v3.10.0 in CI)
  when the tpl context does not contain the .Template object.
