[versions] increase package:platform constraint (flutter#2934)

package:platform required a breaking change in the behavior of FakePlatform in order to enable null safety, but there will be no other breaking changes in 3.X Since this does not affect path provider or local_auth, the pubspec constraint can be increased.
