update_homebrew:dart: also make a dart@2, for Dart 2 migration

This PR modifies update_homebrew to also generate a dart@2 versioned formula. The new file is dropped out right next to the old `dart.rb` file.

The dart@2 formula is a temporary measure to aid application developers
migrating from Dart 1 to Dart 2.

Supersedes https://github.com/dart-lang/homebrew-dart/pull/52.

This looks right by inspection, but I haven't been able to test it yet: my local `dart` environment is all messed up, and I am a Dart newbie. Still, I'm putting this out here as a PR so the discussion from https://github.com/dart-lang/homebrew-dart/pull/52 can proceed.

Closes #33318
