Reference Processing CLI in Tools #633

Which area of the website does this enhancement relate to?

No response

Describe the enhancement

Mention the Processing CLI in the list of Tools that come bundled with Processing.
It will simply state that it exists and how to run ./Processing --help to learn more.
(Or if there is a better place on the website to mention it, let me know.)

Why is this enhancement important?

It makes existing functionality known to the community. It could come in handy for people making scripts to start up Processing sketches in installations etc.

Additional context

I was trying to fix an issue raised in the Processing4 repo that was related to the Processing cli then I realized I don't know how to run it or find any docs about it.
