Generator-jhipster: Update npm packages

[pvliss]

Overview of the feature request

I have lately been dealing with various issues mainly related to ones blocking dev of the Kotlin blueprint and I have noticed that many of the npm dependencies(prod+dev) of both the main generator-jhipster as well as the package.json for the generated apps(only checked React not sure about angular) are lacking behind.

Not sure if this on purpose(if so please let me know and close this) or simply no one has the time to deal with that task but I would like to help in bringing these up to date, at least the ones with minor and patch releases, as major upgrades will need more consideration/careful inspection.

Also while inspecting #9282 I noticed that for React there are some dependencies() used that have been moved/deprecated in favor of new packages(e.g react-addons-css-transition-group has been replaced by react-transition-group ) and should also be fixed accordingly.

I think though that it would be best to update these before the 6.x release rather than later and the more they stay stale the more difficult they are to update.

Please continue if you have time. @DanielFran recently did some related work:

• The Angular dependencies were upgraded (two weeks ago) here: https://github.com/jhipster/generator-jhipster/pull/9241
• There was some work done to React but it required some code changes so it wasn't merged https://github.com/jhipster/generator-jhipster/pull/9243
