Fix Docker build by explicitly installing setuptools

[gabrielgaraujo]

Issues fixed

This PR fixes a Docker build issue where the setuptools package was missing, causing the python3 setup.py install step to fail.

Problem:

The build process was failing at the step where setup.py attempts to run the installation, throwing the following error:

ModuleNotFoundError: No module named 'setuptools'

Solution:

Added setuptools installation as part of the Docker build process to ensure that the package is available when running python3 setup.py install.

Testing:

• Successfully built the Docker image without errors after the change.

@Ourobore can you help with this PR and the build errors. I don't believe they are related to my changes.
