Rename some Docker projects for consistency (#55150)

Apply the :distribution:archives naming convention to some of the Docker
sub-projects, so that we have a more consistent naming scheme.

Also, we've seen some examples of Docker packaging tests failing sporadically
when they try to clean up the temp directory, citing a not-empty
directory. Ensure that any running container is removed before cleaning
up the temp dir, in an effort to avoid this problem.
