- Misc. changes to CI caught during further testing:
1. There should be two shell variables, HELM_VERSION for pulling
down the right version of helm, and HELM_CHART_VERSION, for identifying
generated helm charts.
2. Similarly, `TAG` and `IMAGE_TAG` are two different things.
3. Stop using make/dapper: env vars get lost
4. Skip the RKE Machine config unit test on CI/arm64
