Bump version to 5.4.5

Also bump some dep constraints:

* analyzer ^6.9.0 is required as mockito uses some APIs that were introduced in
  that version.
* That version of analyzer requires a Dart 3.6.0 SDK, so bump that constraint.
* build_runner ^6.11.0 is required to avoid an issue looking for the wrong
  frontend_server snapshot.
