[builder facade] Add appropriate dependencies on IWorkspace

Since the upgrade to Eclipse baseline of 2022-09, it seems that Eclipse
registers the workspace as an IWorkspace object. An exception stacktrace
even recommends depending on this using DS or similar instead of using the
static method ResourcePlugin.getWorkspace(). Adding this dependency fixes
some runtime startup ordering problems.
