[PR] docs: sign digest header in hmac-auth example [apisix]

["leno23 (via GitHub)" <gi...@apache.org>]

leno23 opened a new pull request, #13396:
URL: https://github.com/apache/apisix/pull/13396

   ### Description
   
   Update the `hmac-auth` body-validation example so the generated HMAC signature also covers the `Digest` header:
   
   - compute the request body digest before building the signing string
   - add `digest: ...` to the signing string
   - include `digest` in `headers="@request-target date digest"`
   - refresh the printed header, curl, and response examples
   - add a short note explaining that `validate_request_body` validates the body against `Digest`, and signing `digest` binds that digest to the HMAC signature
   
   Fixes #13395
