Subject: [PATCH] chore: upgrade Ubuntu base image from 18.04 to 22.04 in
 Dockerfile
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Updated the Dockerfile to use Ubuntu 22.04 as the base image instead of
the deprecated Ubuntu 18.04. This ensures we use a more recent and
supported Ubuntu LTS version for better security and package availability.
