DT-1582 AAUser I have a button add slice templates from Slice Zone

The goal is from the Slice Zone header and Slice Zone blank slate be able to click on a button that open the modal to select Slice Templates.

The button would be like the current design without any more information.

The goal is to only display the button if slice templates feature is supported.

It would mean 3 buttons in the header and the blank slate until future iterations.
