Analyzer: stop using NullSafetyUnderstandingFlag in why_not_promoted_test.dart. The CL to add why_not_promoted_test.dart and the CL to remove NullSafetyUnderstandingFlag landed around the same time, so we failed to notice the conflict between them. The fix is easy: since NullSafetyUnderstandingFlag doesn't exist anymore (and isn't needed anymore), we can just remove this use of it. Fixes bot failures with the test `pkg/analyzer/test/id_tests/why_not_promoted_test`.

Dart is:
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.
