The `twenty-twenty-one-ie11-polyfills` script now has a `null` source, and the new `twenty-twenty-one-ie11-polyfills-asset` (which points to the actual `polyfills.js` source) will be loaded only if IE is detected by through the use of `wp_get_script_polyfill()`. Because the original script name remains the same, this change is backwards compatible with any code registering `twenty-twenty-one-id11-polyfills` as a script dependency. Props poena, ismail.elkorchi, peterwilsoncc Fixes #52098.
