Make valkey-py install the correct dependencies in Python 3.11.0 to Python 3.11.3

[nirav-ark-biotech]

I just happened to be using Python 3.11.1 while using valkey-py.

The PR #87 broke my CI/CD pipeline (when upgrading to valkey-py 6.1 bc the codebase, in https://github.com/valkey-io/valkey-py/blob/03320e6b2720a90d1b2ac7946d82bdc4d87f3faa/valkey/asyncio/connection.py#L31

just so happens to check whether or not we're 3.11.3 and above.

If you are in Python 3.11.0 - 3.11.2, you go into the else and this code fails if async timeout is not installed

so we need to still to install async-timeout if python version < 3.11.3

Hi! Thanks for reporting and apologies for the inconvenience. I think that setup.py would also need to be updated. I'll add a commit here for that, so we can make a new release quickly
