[runwhen-local-feedback] kubectl and oc binaries (maybe others?) don't work in arm64 image

[stewartshea]

Observation
This particular issue doesn't appear to break the discovery or cheat sheet rendering functions, but it would render the built-in terminal unpractical.

In docker desktop for mac, we can run the amd64 image and docker desktop will perform the necessary emulation, but it's ideal to support the arm64 build (or do away with it entirely).

Possible Suggestions
See what exists for instructions in the dockerfile to install arm64 compatible binaries of those images. We thought that openshift was already covered here, but it doesn't appear to work - so further logic and testing is required.

Any other details or context

[stewartshea]

It appeared that these binaries weren't really of use to users of this image and so most of the additional tools have been pulled out.
