Adding a script for those 3 commands is a rabbit hole I don't want to open here to be honest.
In general this is not that much typing and scripts are going to be pain to maintain.
To do that properly, you would need to support both Windows and Linux, we don't discriminate contributors even if they make pool life choices. Additionally you have to check if the venv already exists and skip creation, as it will fail.
We could instead include those commands in README if they are not included yet.
