[CAM-13710] The IntelliJ IDEA Camunda Maven Archetypes guide has missing steps

Given:
The Camunda documentation on Maven Archetypes has a section on IntelliJ IDEA usage: https://docs.camunda.org/manual/7.15/user-guide/process-applications/maven-archetypes/#usage-in-intellij-idea.

Problem:
The section on IntelliJ IDEA usage is missing steps on how to add the URL of the catalog file.

Expected:
The section on IntelliJ IDEA usage documents how the URL of the catalog file can be added.
