Upgrade to chevrotain 7

See original GitHub issue

Why ?

We should try to have latest versions of our libs to include easily their improvements (bugs, enhancements, etc.)

What ?

I tried to upgrade, but ran into an error:

There was a conditional inside the cstPostNonTerminal method. It seems to have been removed in newer versions

https://github.com/Chevrotain/chevrotain/blob/v6.5.0/packages/chevrotain/src/parse/parser/traits/tree_builder.ts#L268-L272

Try putting the super call inside the conditional check in the override of the JavaParser

https://github.com/jhipster/prettier-java/blob/main/packages/java-parser/src/parser.js#L80-L81

Starting with 200, which can be increased if it’s a lot of work
