describe review notifications in the registry manifest

The manifest predates the feature: registry UIs rendered the
configuration hints without the review-notifications flag family. The
description now names the capability, and the environment-variable
list carries the enable flag, poll interval, and the three noise
filters with their defaults.

Reaches the registry with the next released tag via the Registry
workflow.
