* Moved `locale-gen en_US.UTF-8` command into the main installation RUN command for efficiency.
* Removed redundant `RUN locale-gen` lines to streamline the Dockerfile.
* Split `apt-get install` command into multiple lines for better readability.
* Updated package list to ensure compatibility with the latest dependencies.

steamcmd update will only apply to root user. If non root user update is still downloaded. This update added 138MB layer to docker container and will probably not be used anyway.
