Add support for monolog/monolog 3.x.x

[bastien70]

With Symfony 6.1, we have the following error when installing the library :

andres-montanez/magallanes 5.0.0 requires monolog/monolog ^2.5 -> found monolog/monolog[2.5.0, 2.6.0, 2.7.0, 2.8.0] but the package is fixed to 3.1.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.

As this is an independent tool you should not add this to the require-dev section of your application. Instead you should use a separate directory for this dependency within your code base - e.g. tools/magallanes/composer.json where you only require this package. This way there cannot be unnecessary conflicts. If you have multiple tools like this you can then use bamarni/composer-bin-plugin to ease the handling of all tools.
