Privacy: Print screen reader text for the "Copy suggested policy text..." action button.

This change switches out `sprintf` for `printf` on the "Copy suggested policy text from..." button screen reader text.  Also, wrap the actual button text in a `<span aria-hidden="true">` to prevent both the button text and the screen reader text from being spoken.
