We should change the description of the property in https://docs.camunda.org/manual/7.14/reference/deployment-descriptors/tags/process-engine/#dmnFeelCustomFunctionProviders to something like:

Define a list of instances of FeelCustomFunctionProvider. You can only set this property programmatically. Read more about it in the user guide.

Also in https://docs.camunda.org/manual/7.14/user-guide/dmn-engine/feel/custom-functions/#process-engine, we should may be give an example code to register this property via plugin.

Note
Registering this property via Plugin works.

We should remove {{dmnFeelCustomFunctionProviders}} property from this page as this configuration does not work out of the box.
