Insert #attributes class inside of form API for bulk operation to identify the field with class and apply the logic in front-end

Problem/Motivation

Inside of bulk operation form there are operations and according to the operation there are fields to be visible. We need to apply the logic in the front-end using JS, and to do that we need to create a class inside of Form API

Steps to reproduce

Proposed resolution

Update the builForm with the new attributes for those fields and update the JS to get those fields using these classes that were added
