[PHPStan] Regenerated baseline

[mnocon]

Target: 4.6, 5.0

PHPStan is currently failing with:

 ------ --------------------------------------------------------------------------------------------------------------------------------------------------------------
  Line   discounts/src/Command/ManageDiscountsCommand.php
 ------ --------------------------------------------------------------------------------------------------------------------------------------------------------------
  60     Class Ibexa\Contracts\DiscountsCodes\Value\Struct\DiscountCodeCreateStruct constructor invoked with 4 parameters, 5 required.
         🪪 arguments.count
  64     Parameter #4 $creatorId of class Ibexa\Contracts\DiscountsCodes\Value\Struct\DiscountCodeCreateStruct constructor expects int|null, DateTimeImmutable given.
         🪪 argument.type

         🪪 arguments.count

The code fixes are done in #2810 , but they cannot be merged yet - because we must wait for 4.6.22 before we merge.

Because of that, I'm adding these issues to the baseline, so that the we don't miss something else important
