purge-docker: remove redundant task

The `remove_packages` prompt is redundant to the `ireallymeanit` prompt
since it does exactly the same thing. I guess the only goal of this task
was to make a break to warn user about `--skip-tags=with_pkg` feature.
This warning should be part of the first prompt.
