Fix `map_annotation` when annotation is `{list,dict}` instead of `typing.{List,Dict}`

[akihironitta]

Fixes this error:

from dataclasses import dataclass
from typing import Dict

from torch_geometric.config_store import register

@register()
@dataclass
class MyClass1:
    something: Dict[str, int]

@register()
@dataclass
class MyClass2:
    something: dict[str, int]
