Set BundleHasStrictIdentifier to false so Rack <=2.6.0 Mac app bundles with identifier `com.vcvrack.rack` are overwritten with the new `com.vcvrack.rack2` app bundle. Set BundleIsRelocatable to true so if a user moves the Rack >=2.6.1 app bundle, the installer will find it by its identifier and upgrade (overwrite) it.
