Why This Fix Works in Production

Trigger: **Description**: Description of your issue, stack traces from errors and code that reproduces the issue
Mechanism: Updates the dependency requirement for async-timeout to use python_full_version for Python 3.11.3 compatibility.
Why the fix works: Updates the dependency requirement for async-timeout to use python_full_version for Python 3.11.3 compatibility. (first fixed release: 7.1.0).

Production impact:

If left unfixed, the same config can fail only in production (env differences), causing startup failures or partial feature outages.

Why This Breaks in Prod

Shows up under Python 3.11.3 in real deployments (not just unit tests).
