Bug 580708 - Running SWTBot Tests fails under Eclipse 2022-09

Use org.eclipse.pde.launching.JUnitLaunchConfigurationDelegate instead
of deprecated
org.eclipse.pde.ui.launcher.JUnitLaunchConfigurationDelegate.
This is to fix broken SWTBOT PDE launch in Eclipse 2022-09.

This change is supposed to work with older Eclipse versions as well
because org.eclipse.pde.launching.JUnitLaunchConfigurationDelegate is
present since Eclipse 3.6.
