ci: upgrade to phpunit 12

Remove soyuka/phpunit fork from all composer.json files and upgrade to
PHPUnit 12.2. Update CI workflow to install PHPUnit before other steps
and configure MongoDB conditional execution. Migrate tests from Prophecy
to PHPUnit native mocking in FieldsBuilderTest and Symfony event listener
tests. Remove unused dataprovider and fix warnings.
