[bug\_fix] ModuleNotFoundError: No module named 'pip' inside a fresh virtual environment

Create the virtual environment with '--without-pip' and then install pip manually, or use 'python -m ensurepip --upgrade'. Alternatively, use 'python -m venv --without-pip' and then 'python get-pip.py'.

Journey Context:
A developer created a virtual environment on a system where the Python installation did not include ensurepip \(e.g., some Debian-based systems\). After running 'python -m venv myenv', the environment was created but without pip. When they tried to use pip inside the environment, they got ModuleNotFoundError. They fixed it by running 'python -m ensurepip --upgrade' inside the venv, which installed pip. Root cause: ensurepip is optional and may be missing on some distributions; venv can be created without pip if ensurepip is not available.
