chore: use matrix generator

[tinect]

There are two errors:

• Fetching class constant class of deprecated class Shopware\Core\Framework\Adapter\Cache\CacheDecorator: tag:v6.7.0 - reason:decoration-will-be-removed - Will be removed Should we add it to the baseline?
• Instantiation of deprecated class Shopware\Core\Maintenance\System\Struct\DatabaseConnectionInformation: tag:v6.7.0 - reason:becomes-internal This might be a problem if it will be internal?

DatabaseConnectionInformation I would parse it on our own

and for that other stuff make an if condition around 😅
