Fixes #8445

The optional chaining and nullish coalescing plugins are now supported by @babel/preset-env, however webpack is currently lacking support for this syntax due to acornjs/acorn#890 and acornjs/acorn#891 it appears.

This issue would happen when using an aggressive browserslist configuration such as last 1 chrome version, as chrome 80 that was recently released includes native support, and therefore this syntax was no longer transformed which would cause webpack to choke.
