fix: Integration fails to setup

[victorkp]

Fixes URL issues for US region users, while still retaining the old URL for non-US users.

This is a replacement for #203, which breaks the URL for non-US users.

@victorkp In my opinion this woud be a better solution if there were to be cases in the future where multiple location based urls are used.

# Starting in 2023, US users need to point at the aoa (Audi of America) URL.
base_url = "https://app-api.live.my.audi.com/vgql/v1/graphql"
usa_url = "https://app-api.my.aoa.audi.com/vgql/v1/graphql"

request_url = usa_url if self._country.upper() == "US" else base_url

req_rsp, rep_rsp_txt = await self._api_request(
    "POST",
    request_url,
    json.dumps(req_data),
    headers=headers,
    allow_redirects=False,
)

AFAIK that’s how it was implemented some time ago. That’s why you have to give the region when you install the integration.
