Deprecation Warning on latest pydantic version

[DominicOram]

Describe the bug
When comparing pydantic models deepdiff uses code that is soon to be deprecated and so a warning is thrown.

To Reproduce
With pydantic>2.11 installed run:

from deepdiff import DeepDiff
from pydantic import BaseModel

class MyModel(BaseModel): ...

difference = DeepDiff(
    MyModel(),
    MyModel(),
)

This produces a warning of the following:

pydantic.warnings.PydanticDeprecatedSince211: Accessing this attribute on the instance is deprecated, and will be removed in Pydantic V3. Instead, you should access this attribute from the model class. Deprecated in Pydantic V2.11 to be removed in V3.0.

Expected behavior
The above produces no warnings

OS, DeepDiff version and Python version (please complete the following information):

• OS: RHEL8
• Python Version 3.11
• DeepDiff Version 8.4.2
