make symfony 7 compatible

[op-euga]

wanted to update to symfony 7 but composer complains:
Problem 1
- mopa/bootstrap-bundle[v3.4.0, ..., v3.4.1] require symfony/console ^4.4 || ^5.1 -> found symfony/console[v4.4.0, ..., v4.4.49, v5.1.0, ..., v5.4.34] but these were not loaded, likely because it conflicts with another require.
- mopa/bootstrap-bundle v3.4.2 requires symfony/console ^4.4 || ^5.1 || ^6.0 -> found symfony/console[v4.4.0, ..., v4.4.49, v5.1.0, ..., v5.4.34, v6.0.0, ..., v6.4.2] but these were not loaded, likely because it conflicts with another require.
- Root composer.json requires mopa/bootstrap-bundle ^3.4 -> satisfiable by mopa/bootstrap-bundle[v3.4.0, v3.4.1, v3.4.2].

could you please make it work with symfony 7

Is there any chance that this will be fixed soon?
