Update fs-extra in packages/create-react-kotlin-app from 1.0.0 to 4.0.0

[dependencies]

Dependencies.io has updated fs-extra (a npm dependency in packages/create-react-kotlin-app) from "1.0.0" to "4.0.0".

4.0.0

Changed

• BREAKING: The promisified versions of fs.read() & fs.write() now return objects. See the docs for details. #436, #449
• fs.move() now errors out when destination is a subdirectory of source. #458
• Applied upstream fixes from rimraf to fs.remove() & fs.removeSync(). #459

Fixed

• Got fs.outputJSONSync() working again; it was broken due to refactoring. #428

Also clarified the docs in a few places.

3.0.0

Added

• BREAKING: Added Promise support. All asynchronous native fs methods and fs-extra methods now return a promise if the callback is not passed. #403
• pathExists(), a replacement for the deprecated fs.exists. pathExists has a normal error-first callback signature. Also added pathExistsSync, an alias to fs.existsSync, for completeness. #406

Removed

• BREAKING: Removed support for setting the default spaces for writeJson(), writeJsonSync(), outputJson(), & outputJsonSync(). This was undocumented. #402

Changed

• Upgraded jsonfile dependency to v3.0.0:
  • BREAKING: Changed behavior of throws option for readJsonSync(); now does not throw filesystem errors when throws is false.
• BREAKING: writeJson(), writeJsonSync(), outputJson(), & outputJsonSync() now output minified JSON by default for consistency with JSON.stringify(); set the spaces option to 2 to override this new behavior. #402
• Use Buffer.allocUnsafe() instead of new Buffer() in environments that support it. #394

Fixed

• removeSync() silently failed on Windows in some cases. Now throws an EBUSY error. #408

2.0.0

Removed

• BREAKING: Removed support for Node v0.12. The Node foundation stopped officially supporting it
  on Jan 1st, 2017.
• BREAKING: Remove walk() and walkSync(). walkSync() was only part of fs-extra for a little
  over two months. Use klaw instead of walk(), in fact, walk() was just
  an alias to klaw. For walkSync() use klaw-sync. See: [Support multiple source paths. #338], [Update core-js requirement from ^3.2.1 to ^3.4.0 #339]

Changed

• BREAKING: Renamed clobber to overwrite. This affects copy(), copySync(), and move(). [Update lerna requirement from ^3.16.4 to ^3.18.3 #330], [Translate README into Korean. #333]
• Moved docs, to docs/. [Update lerna requirement from ^3.16.4 to ^3.18.4 #340]

Fixed

• Apply filters to directories in copySync() like in copy(). [Bump core-js from 3.3.2 to 3.3.2 #324]
• A specific condition when disk is under heavy use, copy() can fail. [Bump fsevents from 2.1.1 to 2.1.1 #326]
