[bug] Type annotated objects in pydantic guards incorrectly transpile to XML

[irgolic]

Describe the bug
When making a guard from a pydantic model, if a Dict has type arguments on it, it transpiles into XML in a way that doesn't work.

To Reproduce

from pydantic import BaseModel
from guardrails import Guard

class CorrectAnswers(BaseModel):
    all_of: Dict[str, str] = {}
    any_of_groups: List[Dict[str, str]] = []
    not_all_of_groups: List[Dict[str, str]] = []
    not_any_of: Dict[str, str] = {}

Guard.from_pydantic(CorrectAnswers)

Expected behavior
XML guards don't support specifying types in objects with arbitrary elements, so it should probably just act like this:

class CorrectAnswers(BaseModel):
    all_of: Dict = {}
    any_of_groups: List[Dict] = []
    not_all_of_groups: List[Dict] = []
    not_any_of: Dict = {}

Library version:
0.2.0

Additional context
This bug will probably be fixed when we migrate to XML-invariant internals.
