python3Packages.asyncpg: fix build and bump minimum Python version

[wackbyte]

Description of changes

I added the package's dependency on async-timeout. Because it was missing, attempting to build it with Python <=3.10 resulted in this error.

The build failures are unrelated to this PR (they fail to build on master as well), so I think those packages are broken.

But latest build https://hydra.nixos.org/build/252816345 is OK. What is broken?

[wackbyte]

It seems like it doesn't fail in python312 and python311, but it does fail in python310 and python39 (and possibly more). I couldn't find a python310 build of the package in Hydra.

[wackbyte]

It's failing in versions prior to 3.11 specifically because of this compatibility code that imports async-timeout for older versions of Python.

[wackbyte]

Ah, looks like the minimum Python version was also bumped from 3.7 to 3.8. I'll add that later.
