Since RTL hook overrides html/portlet/dynamic_data_mapping/js/main.js it should apply the change from LPS-33161 as well in order for the DDL can be saved

Steps to reproduce:

1. Go to Admin -> Content -> Dynamic Data Lists
2. Add a new definition: Manage Definition -> Add
3. Give a name and add a checkbox field
4. Save it

Actual behavior: Error: Your request failed to complete. Please enter a valid XML schema definition.
Expected behavior: The DDL can be saved.
