This is not as simple as proposed in #5576 and also should to be done for the 8.5, 9.6, and 10.5 branches. At this point I do not expect another release from the 10.4 branch.

The PHAR build process for PHPUnit 8.5 and PHPUnit 9.6 performs composer require operations that, of course, modify the composer.json and composer.lock files. The build process needs to be adapter to also roll back the changes to composer.lock. (The composer.lock that is put into the PHAR for #5577 is the right one.)
