[SUREFIRE-1870] Update a dependency of the proposed example

**[Andrea Stedile](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=steddy)** opened **[SUREFIRE-1870](https://issues.apache.org/jira/browse/SUREFIRE-1870?redirect=false)** and commented

https://maven.apache.org/surefire/maven-failsafe-plugin/usage.html

### Using jetty and maven-failsafe-plugin

The example contains this piece of code:

\org.eclipse.jetty\
\jetty-maven-plugin\
\9.2.2.v20140723\

jetty-maven-plugin should be updated to 11.0.0.

+**Please, see the related issue**+, where I describe the motivations for this upgrade, and why the actual example may contain a bug.

---

**Affects:** 3.0.0-M4

Start with the Maven Failsafe usage page linked in the issue and locate the “Using jetty and maven-failsafe-plugin” example. Check the dependency declaration for jetty-maven-plugin and update its version to 11.0.0; the example should use the requested dependency version without the reported bug.
