Paul Berry cbd8a4582c Analyzer: Fix null safety migration error in experimental flag generation ...

It's possible for an entry in `tools/experimental_features.yaml` to
lack an `expired` line, so we need to represent it as a `bool?`.

Avoids a crash when running `dart
pkg/analyzer/tool/experiments/generate.dart`.
