ckeditor5-react can be published in ES6

[Viktor-the-great]

CKEditor 5 Builds are published in the original ES6 format. If environment requires ES5, I need to transpile CKEditor 5 source to ES5 (ckeditor5 doc).
ckeditor5-react are published in ES5 format, so I need to manually filter ckeditor5-react build (in webpack config).

I think ckeditor5-react Builds should be published in ES6 format like other CKEditor 5 builds.

I don't see any reason why we couldn't do that.

All that we need to do is just remove @babel/preset-env from the presets array in Webpack configuration.

All tests pass:

Finished in 1.915 secs / 0.509 secs @ 10:08:39 GMT+0200 (Central European Summer Time)

SUMMARY:
✔ 35 tests completed

Will the change be a BC?

@Reinmar, WDYT?

The other question is why you need this transpilation. Because the support for IE11 is still an open issue and currently it does not work.

Sounds fine to me. Although, I don't know what kind of implications this will have for people who use CKE5 in CRA apps. I guess none, because CKE5 is already ES6 there, so it already needs to be treated with Terser (instead of Uglify) and hence already require changing the configuration. Is that correct? No documentation changes will be required?

No, we don't need to change anything.

Let's do it then.
