Azure integration with Symfony 5.4+

[pan85]

I tried to implement the bundle using my azure container and it looks like it is not working with a higher version of php (8.0 in my case) and Symfony 5.4. There are outdated packages like league/flysystem. I trield to fork your repo and upgrade the packages that you are usning but there are too many dependencies.

Just to mentiion that S3 integration is working as expected and I tried the native ckfinder version by downloading it as a zip, and it work too.
