requirements errors with composer.json require and Sulu 2.5.4

[fgalleron]

Hello I'm setting up a project with the latest version of Sulu (2.5.4) and I'm getting a conflict error.
`Your requirements could not be resolved to an installable set of packages.

Problem 1
- Root composer.json requires sulu/community-bundle ^2.0@dev -> satisfiable by sulu/community-bundle[2.0.x-dev].
- sulu/community-bundle 2.0.x-dev requires symfony/config ^4.4 || ^5.0 -> found symfony/config[v4.4.0, ..., v4.4.44, v5.0.0, ..., v5.4.11] but it conflicts with your root composer.json require (^6.0).`

I really don't know how to solve that issue. I don't what to change the composer.json require since I think that Sulu 2.5.4 needs the ^6.0 version to work fine.

Thank you for your help :)
