Virtual environment tries to use python 3.9 and fails to install deps

[talpr]

I tried running the reproduction tool today, and got errors building the grpcio-tools (gpaste of full error). After some asking around, a colleague mentioned that they'd encountered this too, and the reason was that it was using python 3.9. Forcing the use of 3.8 in install_deps_linux.bash fixes the issues.

Not sure if this is related, but the local installation of python3 is version 3.8.7.

Diff for the (hacky) fix:

can you try with export PYTHON=python3.8 does that work for you?

Yes, that works too, thank you. Is there anyway to fix this in the script itself? It's is hard to tell from the error messages what the exact problem is, and that this would be the solution for it.
