remove incorrect "readonly" example

Browse Source 
The :ro option can only be used for named and bind-mounted
volumes, not on "regular" (unnamed) volumes as explained in
https://github.com/docker/docker/pull/16013#issuecomment-146647216

The example in the documentation actually resulted in a
bind-mounted volume, mounted at "ro" inside the container.

This removes the incorrect example from the documentation.

Docker volumes default to mount in read-write mode, but you can also set it to be mounted read-only.
$ docker run -d -P --name web -v /opt/webapp:ro training/webapp python app.py
### Locating a volume
You can locate the volume on the host by utilizing the 'docker inspect' command.
