Babel polyfill broken in 7.26.10

See original GitHub issue

Specifying

  // ember-cli-build.js
  let app = new EmberApp(defaults, {
    'ember-cli-babel': {
      includePolyfill: true,
    },
  });

will cause the following error on build:

Build Error (SourceMapConcat)

ENOENT: no such file or directory, open '/var/folders/7h/82hn6hyn1bngg96_xvhlmq040000gn/T/broccoli-34311LQfVtgUc1OgD/out-262-broccoli_debug_debug_5_vendor_js/vendor/babel-polyfill/polyfill.js'

I suspect it was an “unclean revert”[^1]: ea752c4 reverted 0d47e8b, but did not revert the bump to @babel/preset-env that was included there. Presumably there’s a difference in what the updated @babel/preset-env is requiring or not for the polyfill.

[^1]: this sounds hilarious 😂
