Description

"Babel 7.8.0 supports the new ECMAScript 2020 features by default: you don't need to enable individual plugins for nullish coalescing (??), optional chaining (?.) and dynamic import() anymore with preset-env." - https://babeljs.io/blog/2020/01/11/7.8.0

We should update zero to latest babel and add an integration test for these features. I think the right change will be here.

Research direction
Examine the file at packages/core/lib/utils/commonDependencies.js to understand current Babel version and configuration. Review Babel 7.8.0 release notes for any breaking changes. Add an integration test that uses nullish coalescing and optional chaining to verify the upgrade. Ensure existing tests pass.
