Python modules (requirements.txt):

• https://pypi.org/project/robotframework/
• latest: 5.0.1
• active: 3.1.2

TODO:

• Upgrade python modules (robotframework, etc) to a newer version.
• The latest version if possible and/or remove the dependency restriction.
• Research dependencies within the repository to verify testing would not be adversely affected.
