PickList: Templates for sourceFilter and targetFilter not working

[infe42]

Describe the bug

The templates for sourceFilter and targetFilter are not working in the PickList component. I tried the old templating method using "pTemplate" and the new templating method using "#". I also tried various spellings including camelCase and lowercase.

The documentation is using lowercase template names on the "Features" Tab and camelCase names on the "API" tab. This is confusing. See: https://primeng.org/picklist
