Bad link to Java SDK from eventing-examples-docexpiry

6.5/eventing/eventing-examples-docexpiry.html (TAB "Java SDK program") link has become stale

I think in 6.0
xref:java-sdk::start-using-sdk.adoc
went to
https://docs.couchbase.com/java-sdk/2.7/start-using-sdk.html

In 6.5 the naming standard / path for the SDK changed (why Hello World?)
https://docs.couchbase.com/java-sdk/3.0/hello-world/start-using-sdk.html

So perhaps we need to update the link at line XX of 6.5/modules/eventing/pages/eventing-examples-docexpiry.adoc to either

xref:java-sdk:3.0/hello-world/start-using-sdk.adoc
