[DOC] - Use of json schema for configuration documenation

Preliminary Checks

• This issue is not a question, feature request, RFC, or anything other than a bug report. Please post those things in GitHub Discussions: https://github.com/nebari-dev/nebari/discussions

Summary

Currently the configuration documentation has been written by hand. I would like us to rely more heavily on the json schema. As an example visit https://json-schema.app/view/%23?url=https%3A%2F%2Fgist.githubusercontent.com%2Fcostrouc%2F603071253cf3f942e480afeb5af37750%2Fraw%2Fd814480005856426052a772a4a63dbefe9e83cf2%2Fschema.json for what is possible.

>>> import nebari
>>> with open('schema.json', 'w') as f:
>>>       f.write(nebari.plugins.nebari_plugin_manager.config_schema.schema_json())

This will render the json schema. We could also choose to export subsections and include that embeded within certain documentation.

Steps to Resolve this Issue

Use json schema within the docs.

Start by reviewing the existing configuration documentation and the schema entry point shown in the issue: nebari.plugins.nebari_plugin_manager.config_schema.schema_json(). Determine which documentation sections should use the generated JSON schema or embedded subsections, then verify that the documented configuration is represented by the schema and renders as expected.
