Unable to create config with submodel named "api"

[voodoo11]

When attempting to create a config with a submodel named "api", an error occurs:

pydantic_settings.sources.SettingsError: error parsing value for field "api" from source "EnvSettingsSource"

How to reproduce:

from pydantic import BaseModel
from pydantic_settings import BaseSettings


class ApiConfig(BaseModel):
    foo: str


class Config(BaseSettings):
    api: ApiConfig = ApiConfig()


Config()

Changing submodel name fixes the problem.
