[dart][dart-dio] Update dependencies (#9122)

* [dart-dio] Update dio

* [dart-dio] Update to dio 4.0.0

* [dart-dio] Fix dependency problems with Dart 2.12 SDK during build

* Revert changes to analyzer

This only fails locally, not sure why. CI only shows a warning.

* Fix compile error after http_mock update
