Project documentation filepicker

As a Studio user, in every feature documentation an icon allows me to use a filepicker.

When I open this filepicker, I can select a document uploaded in my document management space in connect. Once the document is selected and I confirm my choice, the filepicker is closed and I get a markdown url for that document, e.g. https://connect.nuxeo.com/something/123-456-789(Document Title) inside the feature documentation.
