There are no FileNotificationMBean usage examples in OL docs

[Zech-Hein]

Please describe the problem you are having with the documentation. Is information missing, inaccurate, or unclear? Tell us about the context where you encountered the problem so we can understand how to address it.

Request: To add a code snippet example of how to use a FileNotificationMBean .

There seems to be a hole in our docs for this, the only example we have found so far is from a z/OS connect doc: https://www.ibm.com/docs/en/zos-connect/zosconnect/3.0?topic=demand-invoking-filenotificationmbean-from-java-program

There is a Liberty IBM doc that does give some other mbean examples, but not a FileNotificationMBean example.
https://www.ibm.com/docs/en/was-liberty/base?topic=liberty-examples-accessing-mbean-attributes-operations

I think it would be helpful if we had the FileNotificationMBean example added to that page. FileNotificationMBean is applicable to multiple features, including applicationMonitor, config, keystore, and ltpa.
