[bug\_fix] The virtual environment was not created successfully because ensurepip is not available

Install the \`python3-venv\` package \(or \`python3.x-venv\` for the specific Python version\) using the system package manager: \`sudo apt install python3-venv\` \(Debian/Ubuntu\) or \`sudo dnf install python3-virtualenv\` \(Fedora\). The root cause is that Debian and its derivatives remove the \`ensurepip\` module from the base Python installation to comply with their policy of separating system-managed Python components, requiring explicit installation of the venv support package.

Journey Context:
A new developer on Ubuntu 22.04 follows a tutorial to create a virtual environment. They run \`python3 -m venv myenv\` and immediately receive an error: 'The virtual environment was not created successfully because ensurepip is not available. On Debian/Ubuntu systems, you need to install the python3-venv package using the following command: apt install python3-venv.' Confused because they thought Python included venv by default, they search online and learn that Debian and Ubuntu intentionally strip out \`ensurepip\` \(the module venv uses to bootstrap pip into new environments\) from the base Python packages to force users to explicitly declare they want virtual environment capabilities via the distro's package manager. They run \`sudo apt install python3-venv\`, which installs the missing \`ensurepip\` module. Running \`python3 -m venv myenv\` now works perfectly.
