[PRQ#60117] Merge Request for flutter-bin

WithTheBraid [1] filed a request to merge flutter-bin [2] into flutter-artifacts-google-bin [3]: This package claims to provide flutter-target-android, flutter-target- linux, flutter-target-web, flutter-tool (all currently provided by aur/flutter-artifacts-google-bin) which in fact it does not. This breaks the build of other packages actually requiring any of these targets. This first of all breaks the build of the aur/flutter package itself since it depends on the particular targets.
