Fix: SSL Certificate Verify Failed in stripe-python

### Describe the bug With version 11.4.0 I am getting `httpx.ConnectError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1129)`. If I downgrade to 11.3.0 the error goes away. This seems to only happen when running under asyncio. ### To Reproduce ```bash pip install stripe==11.3.0 python <<'EOF' import asyncio import stripe import stripe.checkout def main(): stripe.default_http_client = stripe.HTTPXClient() stripe.api_key = "YOUR_API_KEY" price_id = "YOUR_PRICE_ID" asyncio.run( stripe.checkout.Session.create_async( customer_email="test@test.com", ui_mode="embedded", line_items=[ { "price": price_id, "quantity": 1, }, ], mode="subscription", return_url=f"http://localhost:3000/payment-complete?session_id={{CHECKOUT_SESSION_ID}}", ) ) main() EOF # >> No error pip install stripe==11.4.0 python <<'EOF' import asyncio import stripe import stripe.checkout def main(): stripe.default_http_client = stripe.HTTPXClient() stripe.api_key = "YOUR_API_KEY" price_id = "YOUR_PRICE_ID" asyncio.run( stripe.checkout.Session.create_async( customer_email="test@test.com", ui_mode="embedded", line_items=[ { "price": price_id, "quantity": 1, }, ], mode="subscription", return_url=f"http://localhost:3000/payment-complete?session_id={{CHECKOUT_SESSION_ID}}", ) ) main() EOF # >> see error ``` ### Expected behavior I expect there to be no error using version 11.4.0 of the library. ### Code snippets See above ### OS macOS and Fedora ### Language version Python 3.9.15 and Python 3.12.2 ### Library version stripe-python==11.4.0 ### API version
