Merge not working since upgrading Symfony to 5.4

[vasilvestre]

I generate coverage for two suits, both results output are HTML. It worked at Symfony 4.4 and after some dependencies upgrade it's not working.

Generated by php-code-coverage 9.2.30 using PHP 8.1.29 and PHPUnit 9.6.16 at Fri Jul 5 8:54:36 UTC 2024.

I install pcov like this :

- wget -O phpcov.phar https://phar.phpunit.de/phpcov-8.2.1.phar
- php phpcov.phar merge --text app/coverage-combined.txt app/coverage

The content is this despite coverage in HTML :

Code Coverage Report:  
  2024-07-09 12:01:12  
                       
 Summary:              
  Classes:        (0/0)
  Methods:        (0/0)
  Lines:          (0/0)

With HTML, the coverage is at 0, classes are seen but not the functions.
