Add Github Actions Workflows to automate Helm Chart Releases

[prologic]

This now effectively gives us an official Helm Chart Repo.

Along with #127 we also have a nice looking landing page for it too!

Closes #74

@prologic can we see if we can keep the directory structure as not to break anyone's pipeline that depends on chart being on the root of the repo.

I can try but that will take significant more work...

It shouldn't, but if it does, can you please check all references of docs to the helmchart to ensure they will continue to be valid after this PR is merged.

Thanks @knatsakis Unfortunately this doesn't quite work yet, and I'm working with upstream on this. But I think the problem here in fact is that the structure of this repo was always wrong and we may have to change it in the end. See this comment

@prologic What did you decide? Are you going to change the repo structure? I think I could help with such PR that it works with the current structure.

I'm back on this and I will just restructure our repo to fit within the accept documented structure.
