no-priority-definition and priority-definition zeebe linting rules should be adjusted and associated with properties panel

[Skaiir]

What should we do?

We should ensure that those new defined linting rules are properly handled and associated in the desktop modeler.

Why should we do it?

To ensure that the errors conform to the modeler's style, and are easily visible during editing of the properties panel.

See camunda/bpmnlint-plugin-camunda-compat#170 for details on the rules.
