SpringBoot Debug the Application documentation uses deprecated features

The documentation on how to debug here: https://docs.spring.io/spring-boot/docs/current/maven-plugin/reference/htmlsingle/#run.examples.debug says to use:

<jvmArguments>
  -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005
</jvmArguments>

Since Java8, the -Xdebug support has been dropped. Ref: https://docs.oracle.com/javase/8/docs/technotes/tools/unix/java.html#BABHDABI

While it still works, the better way to do it is:

<jvmArguments>
  -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005
</jvmArguments>

And via the command line:

$ mvn spring-boot:run -Dspring-boot.run.jvmArguments=-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005

You also no longer need the quotes, so the "make sure to wrap that properly" comment can also be removed.

Cheers, and thanks for the awesome Spring Boot product!
