Bootstrap 5.2 requires importing "maps" now, prior to mixins.

Something in webpack, babel, or ts-loader changed that requires
module.exports.resolve.extensions to include js as well, otherwise
babel fails to resolve @babel/runtime/regenerator/index.js

The other major version bumps are primarily dropping Node <14.
