I'm not entirely sure if this is good to go or not. Can't run the example app. The tokenlists package requires pydantic 1. So either I'm missing something with the compat, or we need that to update for the example app to run.

@fubuloubu if you're okay with this being untested, lmk and I'll ✔️ this.

This seems to have some issues with pydantic v2 compatibility. TaskIQ has some internals that allow it to handle pydantic model serialization. And the way it detects which way to go is via the installed package version:

https://github.com/taskiq-python/taskiq/blob/9a6e49fa754f8645793b018a26a8a48f997ae587/taskiq/compat.py#L13-L26

When it tries to call model_dump() on the model to serialize it, it fails with this:

Traceback (most recent call last):
  File "/home/mike/.venvs/silverback/lib/python3.10/site-packages/ape/utils/basemodel.py", line 206, in __getattr__
    return super().__getattr__(name)
AttributeError: 'super' object has no attribute '__getattr__'. Did you mean: '__setattr__'?

I think this might be an issue with the __getattr__() implementation's compatibility with pydantic v2?

Unless we do something like implement model_dump() (and maybe other v2 methods) on Ape core's BaseModel I think this might have to wait until after core has fully migrated to v2.

The only solution I can see it is wait for Ape 0.7 which will have proper v2 support. Sorry - I didn't realize where you were seeing this issue before but now I understand!
