v3.22.1

Summary

In this release, we fixed a regression introduced by PR #7227 that affected customers using the Event Handler utility with nested metadata annotations such as annotated_types or Interval. Thanks to @rtandy for identifying the bug and validating the fix.

We also fixed small bugs in type annotations and in our documentation.

⭐ Congrats @rpivo and @czechnology for contributing to this project for the first time!
