Update a regex in test_aiohttp_request_coroutine for Python 3.14

[musicinmybrain]

What do these changes do?

Based on downstream testing in Fedora Rawhide, the expected message associated with the TypeError in test_aiohttp_request_coroutine has changed for Python 3.14, which results in a test regression on Python 3.14.

E       AssertionError: Regex pattern did not match.
E        Regex: "^object _SessionRequestContextManager can't be used in 'await' expression$"
E        Input: "'_SessionRequestContextManager' object can't be awaited"

This PR conditionalizes the message regex on the Python interpreter version, fixing the regression.

This can’t easily be reproduced in a virtualenv yet: I have to work around Pydantic and uvloop not being installable for Python 3.14, and even after that, pytest segfaults. However, I have tested the patch with Python 3.14 in Fedora.

Are there changes in behavior for the user?

No; users running tests on Python 3.14 will see one fewer failure.

Is it a substantial burden for the maintainers to support this?

No. It may be desirable to remove the if/else and the old regex once Python 3.14 is the oldest supported Python version.
