[Console] Handle hidden "process" with --option without = on ConsoleApplication

[samsonasik]

Per #6876 (comment)

@TomasVotruba @shakaran this is to handle without =:

Before

➜  rector-src git:(main) ./bin/rector --kaizen 5

  Command "5" is not defined.  

After

➜  rector-src git:(handle-hidden-process) ./bin/rector --kaizen 5           
[EXPERIMENTAL] Running Kaizen mode. Only first 5 rules will be applied


                                                                                                                        
 [OK] Rector is done!

@samsonasik Thank you 👍

Could you also add simple CI 1-line test in the Github workflows that this works with "="?

[samsonasik]

@TomasVotruba sure, I added various e2e test for it 👍 7886eb7
