📦 Release web-features@2.16.0

[github-actions]

This is a generated release pull request. Don't merge if you're not ready to carry out the release.

## What's New
* Schema addition: some features, such as the `with` feature, may be annotated with a `discouraged` object. The `discouraged` object marks deprecated, obsolete, or legacy features that web developers shouldn't use in new web pages (according to a standards body).

  **Showing Baseline iconography for discouraged features may confuse developers.** See [the README](https://github.com/web-platform-dx/web-features/tree/v2.16.0/packages/web-features#readme), the [contributor guidelines](https://github.com/web-platform-dx/web-features/blob/v2.16.0/docs/guidelines.md#discouraged), and https://github.com/web-platform-dx/web-features/pull/2388 for recommendations and details.

* 4 features
* 87.2% coverage of BCD
