This updates two polyfill libraries to their latest versions. - `polyfill-library` from `3.105.0` to `4.0.0`. - `formdata-polyfill` from `4.0.0` to `4.0.10`. This will affect the following script handles: - `wp-polyfill-formdata` - `wp-polyfill-node-contains` - `wp-polyfill-dom-rect` These polyfills are no longer used by WordPress Core, but are kept up to date as a courtesy for any plugins or themes still requiring them. See #55547. Built from https://develop.svn.wordpress.org/trunk@53165 git-svn-id: http://core.svn.wordpress.org/trunk@52754 1a063a9b-81f0-0310-95a4-ce76da25c4cd
