Export keywords to be used in generator-jhipster project.

[mshima]

We have a keywords list in generator-jhipster https://github.com/jhipster/generator-jhipster/blob/main/generators/java/support/reserved-keywords.ts which rarely gets updated.

Would be nice if we could import from java-parser since it more maintained.

@clementdessoude Any thoughts on that? I believe it make sense so we do not a«manage a different list on generator side...
