Subject: [PATCH] External Libraries: Update the `whatwg-fetch` polyfill
 library.

This updates the `whatwg-fetch` library from version `3.6.2` to `3.6.17`, the latest current version.

This library is included and registered within WordPress as the `wp-polyfill-fetch` script and is no longer used by WordPress itself.

Props rajinsharwar, hareesh-pillai.
Fixes #59066.
Built from https://develop.svn.wordpress.org/trunk@56389
