This is done by setting the SDK constraint min version in the package's pubspec to 2.9.0 which is the version that CFE currently uses to mean "opt in". However, the pre-built SDK currently checked into the repo can't handle that version. To work around that, this CL has a gross hack to simply omit the language version in the generated package config if the pubspect's version is 2.9. This has the effect of telling CFE to use the current language version, which is what we want, while also allowing us to put the right SDK constraint in the package's pubspec.
