fix(spec): drop the preset entry's reached-by-neither clause from reason

The lint now walks a page's interfaceConfig.filterBy and a lookup field's
lookupFilters, so the reason clause saying both are reached by neither door
is false. The clause is deleted; the sentence ends on the surface's groups.
registry.ts is regenerated with gen:migration-registry.
