<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Build/Test Tools: Replace the deprecated `@babel/polyfill`.
This replaces the dependency of the deprecated `@babel/polyfill` package with the `core-js` package through `@wordpress/babel-preset-default`.
Previously, the file consisted of a generalized group of polyfills, and not all of them were required. This change allows the contents of this file to be built according to the exact needs as dictated by the `@wordpress/babel-preset-default` package, which takes into account the current browser support.
Props gziolo, youknowriad.
