Message:

Script Loader: stop enqueueing some now obsolete polyfills.

Stop enqueueing polyfills such as wp-polyfill-inert (for the inert attribute) and regenerator-runtime (for generator functions), as they are no longer needed, considering the WordPress project's ​browser support policy.

In addition to that, wp-polyfill (essentially core-js) is no longer enqueued as a dependency of react. This was added in [43903] to ensure compatibility with IE 11, which is no longer supported by WordPress. Developers requiring wp-polyfill need to manually add it as a dependency for their scripts.

Props swissspidy, flixos90, adamsilverstein, youknowriad, gziolo.
Fixes #60962.
