Support for boolean JSON Schemas

Context:

Boolean JSON schemas are true and false:

• true passes the validation of any input.
• false fails the validation of any input.

Consider the specs as references:

• https://datatracker.ietf.org/doc/html/draft-wright-json-schema-00#section-4.4
• https://datatracker.ietf.org/doc/html/draft-wright-json-schema-01#section-4.4
• https://datatracker.ietf.org/doc/html/draft-handrews-json-schema-00#section-4.3.1
• https://datatracker.ietf.org/doc/html/draft-handrews-json-schema-01#section-4.3.1
• https://datatracker.ietf.org/doc/html/draft-handrews-json-schema-02#section-4.3.2
• https://json-schema.org/draft/2020-12/json-schema-core.html#name-boolean-json-schemas

How do we apply this in the library:

I would suggest the following changes:

• Whenever a true JSON Schema is transpiled to a type, the transpiled type should be any or unknown (depending on the config).
• Whenever a false JSON Schema is transpiled to a type, the transpiled type should be never

Examples:

{
     "$schema": "http://json-schema.org/draft/2020-12/schema",
      "type": "object",
      "additionalProperties": false,
      "properties": {
        "color": true,
        "kind": true,
        "number": false
      },
      "required": ["color, kind", "number"]
}

should be transpiled to something like:

export interface Foo {
  color: unknown;
  kind: unknown;
  number: never;
}

I know, number: never feels ugly, but never is probably the type which works nicely not only in this simple example but also in more complex ones.

Current behavior:

Boolean JSON schemas are transpiled into their boolean types:

{
  "$schema": "http://json-schema.org/draft/2020-12/schema",
  "title": "Example Schema",
  "type": "object",
  "properties": {
    "foo": true
  },
  "required": ["foo"]
}

is transpiled into:

export interface ExampleSchema {
  foo: true
  [k: string]: unknown
}

instead of

export interface ExampleSchema {
  foo: unknown
  [k: string]: unknown
}
