Scaffold Makefile install/uninstall targets

### Description

Pass in the docker image values into the Helm commands in the install/uninstall Makefile targets and make sure they are working.

Start with the Makefile's install and uninstall targets and inspect the Helm commands they invoke. Verify how Docker image values are represented in the targets, then run the targets or their documented checks to confirm both commands pass those values correctly.
