[FEAT] Stabilize dependencies

[subiabre]

We were facing several issues caused by rogue versions of some core dependencies:

PHP

• Method visibility issue introduced in version 8.3.8 php/php-src#14480
  Impacts php between 8.3.6 and 8.2.20. Fixed php minor version to 19. We really should be on php 8.3 (much more performant, new key features for development and safer), so will keep an eye until it is stable.

Doctrine

ORM 3 was released some time ago now, but the ecosystem is still transitioning slowly. There is really not much benefit for us by using ORM 3 so we will just follow the community's pace with their most stable releases.

• AbstractManagerRegistry: "Call to a member function isTransient() on null" error symfony/symfony#48879
  Bug was bleeding on our tests and making them fail.
• Deprecation: Using ArrayAccess on Doctrine\ORM\Mapping\FieldMapping stof/StofDoctrineExtensionsBundle#480
• The bundle not set automatcly the value to updated_at and created_at columns when persisting data doctrine-extensions/DoctrineExtensions#2774
  Bugs were not allowing us to rely on key dependency stof/doctrine-extensions-bundle to use features such as Timestampable entities.
