Fix helm installation failure and cleanup values organization

[cephasara]

This PR addresses the leftover attribute and command to install a kernel in the pod at runtime. This has been migrated to the Dockerfile itself, so it doesn't take any longer for the pod to start. I accidentally left this in the chart template when I was testing. 😅

Currently, this prevents helm from installing the chart, so this fix is the main reason for this PR.

Additionally, this PR migrates all macOS specific commands out into their own value map so it is a bit cleaner organizationally speaking.

Perfect, thank you again!

I want to add this to Helm ASAP, I think we need an index.yaml file to do so, are you able to whip one up?

[sickcodes]

That would be amazing :) your work is very appreciated!

Hey @cephasara, finally got around to wrapping my head around this, here's what I did:

git clone https://github.com/sickcodes/Docker-OSX
cd Docker-OSX/helm

helm package .
helm repo index . --url https://github.com/sickcodes/Docker-OSX/helm


https://github.com/sickcodes/Docker-OSX/tree/master/helm

However, I'm getting this error:

An error occurred updating the repository: invalid input: error converting YAML to JSON: yaml: line 89: mapping values are not allowed in this context

Do you have any suggestions how to fix this?
