Bug: Wrong type date generated for annotated datetime in pydantic factory

Description

When using an annotated datetime type in a pydantic model, polyfactory generates random dates instead of random datetimes. This leads to unexpected results:

• time is always set to midnight
• breaks custom validators relying on e.g. tzinfo

MCVE

from typing import Optional, Annotated
import datetime
from pydantic import BaseModel, Field, BeforeValidator
from polyfactory.factories.pydantic_factory import ModelFactory


def validate_datetime(value: datetime.datetime) -> datetime.datetime:
    print(type(value))
    assert value.tzinfo == datetime.timezone.utc
    return value


ValidatedDatetime = Annotated[
    datetime.datetime, BeforeValidator(validate_datetime)
]


class MyModel(BaseModel):
    dt: ValidatedDatetime = Field(
        gt=datetime.datetime(2022, 1, 1, tzinfo=datetime.timezone.utc)
    )


class MyModelFactory(ModelFactory[MyModel]):
    pass


MyModelFactory.build()

# => Prints: <class 'datetime.date'>
# => Returns error: AttributeError: 'datetime.date' object has no attribute 'tzinfo'

Steps to reproduce

Create an annotated datetime type
Create a pydantic model with a field of the annotated datetime type
Create a ModelFactory for the pydantic model
Call ModelFactory.build()
