Remove monolog dependency

[Melfo01]

Monolog repository is not used directly by this repository; so we can remove it ;)

Hey @cleptric 👋,

My tests fail with Symfony 6.0. I think the problem is caused by symfony/psr-http-message-bridge package. In master, tests was launched with version 2.3.1, my PR used 6.4 version.

Do you know why and how to fix it?
Same question with PHPStan?

I have nothing against merging these changes, but I fail to understand how it could help with your problem as monolog/monolog is a development requirement and does not affect at all third parties.

Well, at the very least we're testing that it works fine with that major.

Technically speaking, we don't even depend on monolog/monolog in this bundle, but rather on symfony/monolog-bundle, which is needed only for the E2E tests anyway. We could even remove the requirement on the lib imho, I don't see why it would be useful to keep it.

I'm sorry, the issue wasn't caused by this repository.

However, I'm glad that it sparked a discussion on the necessity of having monolog repository in the dependencies.
I searched the code for dependencies with Monolog, and I didn't find anything either. If you'd like, I can remove this dependency in this pull request?

Yes please, that would be cool!
