closes #51787
changes in the core/deployment/src/main/java/io/quarkus/deployment/pkg/NativeConfig.java allowed me to test this PR, but I think it is also an improvement, so I kept it...

I have tested it and saw that newly there is a tooltip in the generated config file:
mvavrik@fedora:~/sources/quarkus/docs$ cat ./target/quarkus-generated-doc/config/quarkus-core_quarkus.native.adoc | grep "off all monitoring"

• `none` for explicitly turning off all monitoring features
