Add support for Processing 4 to IntelliJ IDEA


On 9 August 2021 there was a release of Processing 4.0 beta 1:

" We're using Java 11, which should be faster, more up to date, and a lot more compatible with newer machines."

Until September 2021 Java 11 was the last LTS release. Now it is Java 17.

Please test if Processing 4.0 beta 1 works out of the box with latest IntelliJ IDEA.

Please consider whether changes to Processing 4.0 repository or IDEA are necessary to make usage of Processing 4 easy with IDEA.
