[dwds] Deps cleanup (#2830)

After all the changes for the migration into the Dart SDK there was
some lingering cleanup to do in the pubspec.

* Removed unused dependencies on `shelf_packages_handler` and `shelf_static`.
* Removed unused dev_dependency on `args`.
* Moved `web` from dependencies to dev_dependencies.
* Removed dependency_override on `sse`.

This minimizes the diffs while we are still copying between github
and the Dart SDK to keep them in sync.

* rebuild with latest dev SDK
