Remove py dependency from recipe

[jcollado]

py is no longer needed by nox code according to:
https://github.com/wntrblm/nox/blob/main/CHANGELOG.md wntrblm/nox#647

Not installing py in the first place is a good way avoid this vulnerability:
pytest-dev/py#287

For the builds that failed, I see the following error:

zstd.ZstdError: zstd compress error: Allocation error : not enough memory

I don't know if there's a way to change the instance size to fix the problem.

Turning it off an on again seems to have done the trick @jcollado 😀
