Delete JS tooling

[hohwille]

As suggested by @maybeec in issue #344 we should drop this section from the documentation:
https://github.com/devonfw/devon4j/blob/master/documentation/guide-client-layer.asciidoc#javascript-for-java-developers

Any feedback if that is common sense and not needed by anyone anymore, or is missplaced in our Java stack devon4j is welcome as well as feedback that you find this valuable and vote against dropping it.

Maybe devon4j is not the place people will look for this info if trying to make sense of the JavaScript ecosystem... I would vote for not dedicating effort here...

As it explains the JS ecosystem for Java developers I would not know where else to put it. Also I think we should not waste effort here. So either do nothing or simply delete.

I would also vote for deleting this section. I do not see the benefit. If someone searches for such a comparison he'll find with a few clicks. https://blog.angular-university.io/javascript-for-java-developers/
This even shows that there's more than excahnging jvm with node.js and mvn with npm

[hohwille]

IMHO https://blog.angular-university.io/javascript-for-java-developers/ is an example for a bad hit as it comes with a long text explaining what is the difference between java and javascript while the section discussed here gives you an overview of the ecosystem and tooling at a glance. In the end with this argument we can delete the entire devonfw documentation as you can find all the knowledge somewhere already on the web if you search hard enough...

However, I am happy to approve and merge a PR removing the section if someone feels like doing this.
