chore(tasklist): update Tasklist with monorepo configuration

[houssain-barouni]

Which problem does the PR fix?

same as in #1647
Starting from 8.6, Tasklist will be distributed together with Zeebe and Operate as a Single JAR (Distribution). By that, the Tasklist configuration is part of the application.yaml file and no longer in application.yml:

• renaming Tasklist containers volumeMount path from */application.yml to */config/application.yaml
• Removing volumeMount /app/resources/application.yaml. It was used for Tasklist docker images built with JIB plugin (applicable to Tasklist versions: [8.3.0, 8.3.5), [8.2.0, 8.2.20), [8.1.0, 8.1.22)).
• Replacing the deprecated brokerContactPoint with gatewayAddress property.
