pre-commit hooks fail in devcontainer

[sophokles73]

Execution of the pre-commit hooks fails in the devcontainer:

A search on the web found some indication that this is due to Python 3.10 on Debian based distros being incompatible: pre-commit/pre-commit#2299

Thanks for point out this issue. We will solve this.

I was able to solve the issue in my local workspace by making sure that the python3-virtualenv and python3-distutils packages of the underlying linux distribution are being installed in the dev container's base image and then adjusting the version of virtualenv in the requirements-dev.txt file to 20.13.* in order to keep using the version that has been installed using the apt tool during (base) image build time.

see pypa/virtualenv#2415 for reference
