Microvenv is not being used on Codespaces

[luabud]

Steps to reproduce:

1. Go to a Microsoft Python repo, e.g. https://github.com/microsoft/python-sample-vscode-django-tutorial
2. Create a Codespace
3. Run the "Python: Create Environment" command and select a Python environment that fails to create a virtual environment when run in the terminal. In my case, it was Python 3.8 at /usr/bin/python3

 ➜ /workspaces/python-sample-vscode-django-tutorial (master) $ python3.8 -m venv .venv
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 python3.8-venv

You may need to use sudo with that command.  After installing the python3-venv
package, recreate your virtual environment.

1. See that the environment creation fails, as microenv isn't used. It seems that it's because there is a venv module under /usr/bin/python3, despite the command failing. The .venv folder is created successfully (with no activation script), but it fails.

@brettcannon How do you recommend we handle this case? Basically there is venv installed in codespaces but not properly?.

[karthiknadig]

Here is our option, if we detect no_pip, we use --without-pip and install pip from pip.pyz?

[karthiknadig]

Ok it is worse than that. So codespaces has, venv and pip but venv is not properly installed. It does not have ensurepip.

According to this: https://pip.pypa.io/en/stable/installation/#ensurepip ensurepip should be there but in code spaces it isnt.
