from_attributes=True does not recognize properties on StripeObject #12199

Initial Checks
- I confirm that I'm using Pydantic V2
Description
When attempting to create a Pydantic model to pull attribute values from a StripeObject returned from the Stripe SDK, I ran into the issue where the stripe_account property present on the StripeObject is not recognized.
>>> from pydantic import BaseModel, ConfigDict
... import stripe
...
... class ExampleModel(BaseModel):
... model_config = ConfigDict(from_attributes=True)
...
... stripe_account: str
...
...
... class Example:
... @property
... def stripe_account(self):
... return "acct_foo"
...
...
... # This works as expected.
... example_obj = Example()
... print(ExampleModel.model_validate(example_obj))
...
... # This fails unexpectedly
... stripe_obj = stripe.StripeObject(stripe_account="acct_asdf")
... print(ExampleModel.model_validate(stripe_obj))
...
stripe_account='acct_foo'
Traceback (most recent call last):

>>> hasattr(stripe_obj, "stripe_account")
True

'acct_asdf'The only thing I could think of is that the way the StripeObject is typed is somehow causing issues: class StripeObject(Dict[str, Any]):
