Missing `List` in the generated code

[huan]

betterproto version: v2.0.0b2

Reproduce steps:

git clone git@github.com:wechaty/grpc.git
cd grpc/python
make install
make generate
cat src/wechaty_grpc/wechaty/__init__.py

We generated the following code:

# ...
from typing import AsyncIterable, AsyncIterator, Iterable, Optional, Union
# ...
    async def contact_phone(
        self, *, contact_id: str = "", phone_list: Optional[List[str]] = None
    ) -> "puppet.ContactPhoneResponse":
# ...

As we can see: there's a List in the code, but there's no List imported from typing.

This is a known issue and should be fixed by #183

Got it, thank your very much!

Close this issue because it's a duplicated one.
