feat!: use type aliases instead of RootModel for root schemas (#51)

* feat!: use type aliases instead of RootModel for root schemas

Avoids generating classes with 'root' fields for schemas that don't define an object at the root (like Amount). Instead, they are generated as TypeAliasType using Annotated with Field for validation.

This is a breaking change for any client code that was instantiating these root models as classes.

* chore: bump version to 0.4.2

* style: fix end of file newlines in generated __init__.py files
