Add GitHub workflow for Ubuntu build; remove

token, update submodule

Introduced a new GitHub Actions workflow to automate Python package
builds on Ubuntu environments upon push or pull request events. This
addition ensures the compatibility of the package on the Ubuntu platform
and streamlines the continuous integration process.

Updated the limedriver submodule to the latest commit, keeping the
project in sync with recent upstream changes and maintaining the
integrity of external dependencies.
