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.
