chore: remove unnecessary apt-get clean in Dockerfile (DIYgod#5958)

This image is built from the official Debian image as upstream, so there is no need to do apt-get clean manually. Ref: - https://docs.docker.com/develop/develop-images/dockerfile_best-practices/#apt-get > Official Debian and Ubuntu images automatically run apt-get clean, so > explicit invocation is not required.
