chore: update TS and JS init templates to consistently use ES6 imports

End Commit Message

I've recently updated the TypeScript code snippets in the AWS CDK Developer Guide to use ES6-style imports so they can be auto-translated to JavaScript using Babel. (Babel won't translate the older style require() imports.)

Since the Guide snippets are (at least in theory) what users would see when working in a project they created using 'cdk init' and a template, let's update the templates to use ES6 imports.

There are a fair number of old-style imports in the various READMEs as well; I'll update those in a separate PR.

This actually broke the JS init templates since Node still doesn't actually support ES6 imports. I experimented with using the esm module, which allowed the JS app to run, but Jest was still broken. The Jest issue also affects the TS init templates.

So I'm going to revert most of this PR. Unfortunately, these changes made it into a release.

@jerry-aws - yes I can confirm we have a regression with JS templates. What's the Jest issue? I'm able to init and run my templates fine in TS

@shivlaks Looks like the Jest issue doesn't affect TS as I thought; the tests are .ts files so tsc will convert the imports to what Jest wants.

Still, no loss to revert the whole PR.
