Put the defaults in a JSON file

[clizbe]

• Store schema in a JSON file #992
• Fix Tulipa so it uses the file (untangle OBZ pipeline)
• Tell the user how to overwrite the defaults

Start with the defaults file Diego has drafted here in function get_default_values:
https://github.com/TulipaEnergy/Tulipa-OBZ-CaseStudy/blob/main/utils/functions.jl

Also consider:

• Implement data validation #461

One option is to have a JSON file that has the schema, description of the parameters, recommended units, and defaults. Issue #992 will also help with #1038 since it can be reused to print it in the docs.

Yes I looked up how one of the solvers stored their defaults, and it was something like this. Although I think theirs were just in a markdown file.

Closed by #1054.
Still need to make features explicit so it doesn't just infer if data is present/missing, but that continues with #996
