Previously custom launch config tabs could cause a Class Cast Exception
in the Launchbar's edit launch config dialog if they did not use the
GridLayout. Since ed1e058 the launchbar dialog no longer tries to give
the tab control GridLayoutData, avoiding the problem and allowing custom
tabs to use whatever layout they wish.
This change updates the launchbar UI tests to Junit 5 and adds a new
SWTbot test to verify the dialog no longer throws a CCE in this case.
