• Update of Continuous Integration Setup
  The changes in this pull request made adjustments to our continuous integrations actions workflow. We've introduced a new command in the 'ci.yml' configuration file. What it does is it makes sure that our package manager tool (apt) has all the latest patches and updates before we go ahead to install any dependencies our project might need. This is important to ensure we're not facing avoidable issues or security risks due to outdated tools during our automated testing or build processes.
