JSON Schema integration

[jassielof]

I have a JSON schema for the Typst manifest (typst.toml) in https://github.com/jassielof/json-schemas/blob/main/docs/typst.yaml.

So, I'm wondering if you would like your tool to be added to the tool section? As a reference on how there's the pyproject schema https://www.schemastore.org/pyproject.json, I'll just add the reference of your schema in the shema.

There is already a tool section yeah, I don't think we need to add this to the schema
Imo, it's reserved to typst, but if the author thinks that's a good idea, we can discuss it later when the tool section of utpm will be stable!
