Adds scripts for generating json schemas for humans

[Tomaz-Vieira]

Adds scripts for generating json schemas for humans, as well as an entry in build.yaml to do it automatically with the other docs. One option (link_to_reused_ref) was causing encoding errors when writing out the HTML. This is marked as deprecated somewhere else in the json-schema-for-humans library code and it might not be in the tested paths. I can investigate that in later PRs if we care enough about it.

This PR also fixes the broken link pointing to the raw json schema.

I think the issue with link_to_reused_ref might be that we have recursive types in our spec

Note: If this option is off and the schema contains recursive definitions, the generation will crash!

So ideally we get rid of the recursive definition (it is probably the yaml dict definition for the config field).
There we could just limit the recursion depth.

Because for the docs it is really unintuitive and confusing to have these references across the docs.

I don't think we should be adjusting the spec just for the sake of fitting in with a tool for generating documentation. If we can't make this produce what we want, we can just find a different tool that does

I was thinking we shouldn't allow infinitely deeply nested custom tool config anyway...
This tool we found is great and this is a minor, meaningful change. Let's go ahead and make it work with this tool (and this config)
