Add sudo to Docker commands in README

[wikmor]

Ensure the commands work for all users, including those who haven’t configured Docker for non-sudo access.

Hi! Thanks for your suggestion.

However, I'm not too keen on adding sudo to all docker commands, as It's up to the user to set up proper docker usage/access permissions on their hosts.

If you have your used added to the docker group (as it's recommended, only to grant execution permissions on the docker CLI, and not on the whole system), then you don't need sudo to run docker. Root should only be needed to add yourself to the docker group.
In environments where the user executing these commands are not the system owner / root user, they wouldn't be able to run the commands with sudo, but the root owner / sysadmin can add the user to the docker group and the commands should work as they were written before.
