Fix CONTRIBUTING.md instructions to install multiple Python versions (#5015)

## Summary

I noticed the command to install multiple Python versions was wrong as
it was failing cause `toolchain` is not a known command.

I looked in the `ci.yml` workflow to see which command is used there and
updated the instructions accordingly.

## Test Plan

I just ran the command locally. :)
