fix: resolve Symfony Console add() method deprecation

[KIKOmanasijev]

Summary

Resolves Symfony Console deprecation warnings by simply overriding the deprecated add() method to delegate to addCommand().

Problem

Since symfony/console 7.4: The "Symfony\Component\Console\Application::add()" method is deprecated and will be removed in Symfony 8.0, use "Symfony\Component\Console\Application::addCommand()" instead.

Actual error from the tests:

ErrorException: Since symfony/console 7.4: The "Symfony\Component\Console\Application::add()" method is deprecated and will be removed in Symfony 8.0, use "Symfony\Component\Console\Application::addCommand()" instead.

Solution

• Override the add() method in Illuminate\Console\Application
• Delegate to addCommand() to maintain Laravel's command registration logic
• Preserve backward compatibility while eliminating deprecation warnings

We will look into this when we approach the Laravel 13 release. As of now, we are targeting support for both 7.4 and 8.0 for Laravel 13 so ideally we don't want to have to add (support) deprecated method
