feat: add form-json-schema package

[pinussilvestrus]

Related to pinussilvestrus/form-json-schema#6

Adds the form-json-schema to the form-js monorepo.

Todo:

• Add $schema to our example files
• fixup failing windows CI

[pinussilvestrus]

Our CI has some troubles currently, I will retry later.

Windows CI currently failing due to nodejs/node#50136

[pinussilvestrus]

We probably need to make the schema generation scripts a bit more robust on Windows

Resolved the broken Windows build by downgrading json-schema-ref-parse (cf. APIDevTools/json-schema-ref-parser#303)
