Pull Request — Semgrep Rule Fix

• Rule ID: missing-user-entrypoint
• Rule Message: By not specifying a USER, a program in the container may run as 'root'. This is a security hazard. If an attacker can control a process running as root, they may have control over the container. Ensure that the last USER in a Dockerfile is a USER other than 'root'.
