test: use python instead of python3

[behnazh-w]

We have made Python 3.11 a requirement for our development environment and use python to run. This PR replaces python3 with python in develoment scripts to be consistent.

Hmmm I wonder if it's better to change everything to python3 instead 🤔. Not that python in this case is wrong, because we have indicated that we should run everything inside the dev environment created with Python 3.11.
I think python3 is still correct and would be more specific than python. When the reader/developer look through the snippet with python3 in isolation, it would be more clear in my opinion. Otherwise, everything looks good to me.

I think we would need to change the same for integration_tests.sh too.

Not sure how I missed that :-)

No, I don't think it's necessary anymore to use Python 3. Python 2.7 might be still supported in some places but it's rare and since we make it clear we use Python 3, it's fine to avoid repeating python3 everywhere.

LGTM. Thanks!
