Issue:
Bug: Required fields in TypedDicts throw exceptions
### Description

Hello, thanks for this super useful library! I was trying out polyfactory with some TypedDicts and it throws an exception. Not sure if this should be classified as a bug or a feature request, but wanted to bring it to your attention in any case.

### URL to code causing the issue

_No response_

### MCVE

```python
from typing_extensions import TypedDict, Required
from polyfactory.factories import TypedDictFactory

class Foo(TypedDict, total=False):
    name: Required[str]
    bar: str

class FooFactory(TypedDictFactory[Foo]):
    __model__ = Foo
```


### Steps to reproduce

```bash
Run `FooFactory.build()`, and I get the exception: `TypeError: Required accepts only a single type. Got (<class 'str'>,).`
```


### Screenshots

### Logs

_No response_

### Release Version

Version: 2.10.0
