docs: Issue in page Configuration. reference.conf 404

[kehao95]

I would like to report an issue in page https://java-driver.docs.scylladb.com/scylla-4.15.0.x/manual/core/configuration/index

Problem

the driver JAR comes with a reference.conf file that defines the defaults.

The reference.conf is missing

Probably should lead to this file: https://github.com/scylladb/java-driver/blob/scylla-4.x/core/src/main/resources/reference.conf
