cb0f56f131
This updates the `whatwg-fetch` library from version `3.6.17` to `3.6.20`, the latest current version. This library is included and registered within WordPress as the `wp-polyfill-fetch` script but is no longer used by WordPress itself. Updates are provided as a courtesy, and all projects using this polyfill should reevaluate usage. Props manooweb. Fixes #60514. Built from https://develop.svn.wordpress.org/trunk@58860 git-svn-id: http://core.svn.wordpress.org/trunk@58256 1a063a9b-81f0-0310-95a4-ce76da25c4cd
