feat: adds support for optional packages in pylic job

# Check the package repo on how to configure this job

# https://github.com/sandrochuber/pylic

# Be warned that this only checks installed packages.

# This job does not install optional dependencies and there

# is currently no reliable method to detect these.

# Add packages to the EXTRA_PACKAGES variable to install these.
