Bug: List[Literal[..]] throws TypeError

[Simske]

Description

factory.build() fails for models with a field declared as List[Literal[...]] because issubclass() doesn't support checking Literal types.

A PR with a proposed fix will be opened shortly.

URL to code causing the issue

No response

MCVE

from dataclasses import dataclass
from typing import Literal, List
from polyfactory.factories import DataclassFactory

@dataclass
class Foo:
    bar: List[Literal["Hallo", "Hello", "Hola"]]

class FooFactory(DataclassFactory[Foo]):
    __model__ = Foo

print(FooFactory.build())

Steps to reproduce

1. Create model or dataclass with a field with type `List[Literal[literal_values]]`
2. Create factory for model
3. Use factory to generate object from model
