Clarify in docs that docker tag doesn't publish

I am attempting to push a tag to a private repository. The documentation for `docker tag`  has an explicit example to for how ["To push an image to a private registry"](https://docs.docker.com/engine/reference/commandline/tag/#tag-an-image-referenced-by-name). My colleague clarified that this command does not in fact push anything, so I thought this PR might save some future novice the same confusion.
