We plan to enable inclusion of a new HTTP header for all webhooks that are configured with a secret. The new header computes a signature for our webhook payloads based on SHA-256 instead of the less-secure SHA-1.

https://github.com/github/hookshot-go/pull/610 added the feature (disabled behind a flag) and https://github.com/github/hookshot-go/pull/612 will enable inclusion of the new header once it's merged.

This PR updates our recommendation for verifying webhook payloads to use the new SHA-256-based signature. We mention the existence of the old header just to minimize any potential confusion, and make it clear that we don't plan to eliminate it.
