Contao 5.1 Support

[denniserdmann]

Contao 5.1 requires Symfony 6, while the grid extension requires Symfony 5

composer update -W
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - symfony/config[v5.0.0, ..., v5.0.8] require php ^7.2.5 -> your php version (8.1.10) does not satisfy that requirement.
    - Root composer.json requires contao/manager-bundle 5.1.* -> satisfiable by contao/manager-bundle[5.1.0].
    - Root composer.json requires erdmannfreunde/contao-grid-bundle 2.0.2 -> satisfiable by erdmannfreunde/contao-grid-bundle[2.0.2].
    - erdmannfreunde/contao-grid-bundle 2.0.2 requires symfony/config ^5.0 -> satisfiable by symfony/config[v5.0.0, ..., v5.4.19].
    - You can only install one version of a package, so only one of these can be installed: symfony/config[v2.2.0, ..., v2.8.52, v3.0.0, ..., v3.4.47, v4.0.0, ..., v4.4.44, v5.0.0, ..., v5.4.19, v6.0.0, ..., v6.2.5].
    - Conclusion: install symfony/config v6.1.11 (conflict analysis result)

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
