Remove possibly confusing non-standard goals from example

In the perform goal example page
http://maven.apache.org/maven-release/maven-release-plugin/examples/perform-release.html
the following example configuration is found:

<goals>deploy assembly:single</goals>

I think this should be removed as it has nothing to do with the subject being explained (specifying profiles) and the "assembly:single" goal should be considered a nonstandard goal for a release (it should be bound to the build lifecycle instead). It could confuse people and also possibly make someone think that this is a good practice.
