[json schema] Do not throw errors when parsing non annotated parameters

[h-mayorquin]

This comes from the IBL project.

Summary:
If someone creates their own interface (inherits from BaseDataInterface) but does not annotate the __init__ function of the interface the validation will throw an obscure error:

self = <pydantic.json_schema.GenerateJsonSchema object at 0x77dfd6ff52d0>, schema = {'cls': <class 'inspect._empty'>, 'metadata': {}, 'type': 'is-instance'}
error_info = "core_schema.IsInstanceSchema (<class 'inspect._empty'>)"

    def handle_invalid_for_json_schema(self, schema: CoreSchemaOrField, error_info: str) -> JsonSchemaValue:
>       raise PydanticInvalidForJsonSchema(f'Cannot generate a JsonSchema for {error_info}')
E       pydantic.errors.PydanticInvalidForJsonSchema: Cannot generate a JsonSchema for core_schema.IsInstanceSchema (<class 'inspect._empty'>)
E

================================================================================================ short test summary info =================================================================================================
FAILED tests/test_minimal/test_utils/test_get_json_schema_from_method_signature.py::test_get_json_schema_from_method_signature_unannotated - pydantic.errors.PydanticInvalidForJsonSchema: Cannot generate a JsonSchema for core_schema.IsInstanceSchema (<class 'inspect._empty'>)
==============================================================

The fix, in my view, is to omit validation when the user does not annotate their signature parameters as there is nothing to validate. I added a fix and a test here.
