Enhancement: Support non-mutable Mapping containers

### Summary

Currently [`handle_collection_type`](https://github.com/litestar-org/polyfactory/blob/f270b0fb46f36b32db0a1c9f9d2cea25c59b8f22/polyfactory/value_generators/complex_types.py#L15) only supports `MutableMapping`s, could support for non-mutable `Mapping`s also be added? I am personally trying to use this alongside the `frozendict` pypi package.

### Basic Example

You could make a factory for e.g.
```python
@dataclass
class Shop(frozen=True)
prices: MyImmutableMapping[str, int]
```
where `MyImmutableMapping` is a subclass of [`Mapping`](https://docs.python.org/3/library/collections.abc.html#collections.abc.Mapping). Currently this will raise
```
NotImplementedError: Unsupported container type:
```

### Drawbacks and Impact

Very few drawbacks in my opinion: changes should be small and isolated and adds functionality many users could benefit from.

### Unresolved questions

_No response_

Start in polyfactory/value_generators/complex_types.py at handle_collection_type, where MutableMapping support and the Unsupported container type error are described. Add support for non-mutable Mapping subclasses, then verify that a factory can build the immutable mapping field in the Shop example without raising NotImplementedError.
