Stricter typing for createHeadlessForm

[titivermeesch]

createHeadlessForm currently relies on JSONSchemaObjectType as schema input type and Fields as output type which does not provide any concrete JSON schema typing whatsoever.

It would be handy if createHeadlessForm accepts types like the ones coming from @types/json-schema as input and some well defined typings for the Fields type.

I see there are already TODOs in the codebase for this but still wanted to track it more explicitly here as well.

Hi @titivermeesch! Indeed, we are working on better typing Fields - #185 - It's with @eng-almeida :D

As for accepting types, what do you have in mind? Do you mean generics to pass more strict types for possible JSON Schemas? Or something else?

json-schema has a well defined schema, so I would expect that the entry function also expects a json-schema type, this is more for internal type reinforcement I guess, not for the end user per say.
