Support Symfony 7

Otherwise no changes.

Stable base libraries

Make it possible to use the stable versions of squirrelphp queries + entities, even if this bundle is not marked as quite stable yet. We need to first refactor squirrelphp/queries-bundle and then check if we need to adapt anything in this library before marking it as a v1.0 release.

Support Symfony 6 + fix tests for PHP 8.1

v0.12.1

Add missing types for Symfony 6

Set minimum PHP version to PHP8

• Upgrade squirrelphp dependencies which have already
    been upgraded to PHP8 and slightly adapted
• Use new attributes instead of previous annotations
    (annotations are gone)
• Adjust the documentation slightly to reflect the changes

New DBAL 3.0 version

v0.11

Upgrade underlying dependencies for DBAL 3.0

v0.10: Adjust version for entities component

Also update tests to use the new name of the entity
constructor trait.

v0.9

Add PHPCS rules & adjust PHP version

v0.8

Increase underlying library versions

Leverage PHP 7.4 features

• Use new version of entities component, which is the basis for this bundle
• As that component is now PHP 7.4 only, we make this package PHP 7.4+ only too

v0.6.1: Enforce Symfony 5 & switch to composer-bin-plugin

We mandate Symfony 5.0 or higher because of slight API
changes reflected in associated packages (entities and
queries-bundle).
