Title: Update the documentation to to clarify random port mapping when using -P on docker run

The documentation for `docker run` does not clearly explain that using `-P` will map exposed ports to a random high port on the host.

Although this is documented in , it should also be clearly specified in the `docker run` documentation as it's confusing for users (see as an example).
