Remove duplicate permission items in index-v2

Hi there.

I found that F-Droid client doesn't show the duplicate permission items, but the website does. I searched the code and found the duplicate items exists in the index file. The client doesn't show them because it make sure each permission item is unique when showing it, but the website and the Jekyll plugin doesn't have such code.

Here are some helpful links:
App with duplicate permission items
F-Droid client code for unique permission items

To resolve this, I want to remove the duplicate permission items when creating the index. Would it be acceptable?
