Make examples/catalog instructions a bit less confusing (#24252) 
Make the examples/catalog instructions a bit less confusing:
* Make the README.md file provide explicit instructions about how to
  run each example.
* Try to clarify that the lib/main.dart message is instructional and
  not an error message.

Additionally, adjust examples/layers/lib/main.dart to be consistent
with examples/catalog/lib/main.dart.

Fixes #22640.

Testing Done:
* Ran `flutter run` from examples/catalog and from examples/layers,
  saw the updated message.

Examples of Flutter's layered architecture

This directory contains a number of self-contained examples that illustrate Flutter's layered architecture.

  • raw/ These examples show how to program against the lowest layer of the system. They manually receive input packets and construct composited scenes.

  • rendering/ These examples use Flutter's render tree to structure your app using a retained tree of visual objects. These objects coordinate to determine their size and position on screen and to handle events.

  • widgets/ These examples use Flutter's widgets to build more elaborate apps using a reactive framework.

  • services/ These examples use services available in Flutter to interact with the host platform.

To run each example, specify the demo file on the flutter run command line, for example:

flutter run raw/spinning_square.dart
flutter run rendering/spinning_square.dart
flutter run widgets/spinning_square.dart
