Update docker base image

viniciusd commented 4 months ago

The current base image, Ubuntu 20.04, comes with gcc 9, which can't compile the code base.

Upgrading it to Ubuntu 22.04 provides us with gcc 11, which handles the more modern features used in the project

Building the current image with docker build -t verifier . gets:

Upgrading the base image and, consequently, GCC, makes it possible to build the image successfully.

This is a follow-up work on #605 to get the docker image functional
