Sample request: Activity log filtering

[cretz]

Describe the solution you'd like

Show how to attach a filter to activity.logger and have it filter out the error warnings that usually appear for failed activities if, say, the exception is of a certain type.

Hi maintainers, I’d like to work on this issue. I plan to add a focused sample showing how to attach a logging filter to activity.logger to suppress expected activity-failure warnings for a selected exception type, along with deterministic tests and usage documentation. If this direction looks right, could you please assign the issue to me? For context, my earlier contribution #343 has been reviewed and merged. Thanks!
