Remove js-interop workaround

Dart 3.3 had the problem of some JS-interop methods declared to return a `JSBoolean` actually returning a Dart `bool`, causing compilation errors. Now that https://github.com/dart-lang/sdk/issues/55024 has been fixed in Dart 3.4, the workarounds introduced to fix the issue can be reverted.
