Subject: [PATCH 2/6] refactor: remove core-js and core-js-pure dependencies
 (#2637)

* core(cleanup): remove core-js and core-js-pure dependencies

The polyfills previously provided by these dependencies can be fulfilled by other existing dependencies of axe-core

* Restore conditional check around Promise polyfilling

* Remove redundant `WeakMap` declaration presence check
