[TASK] Use Connection instead of PDO

In Doctrine DBAL v4, as described in the [documentation](https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/ApiOverview/Database/QueryBuilder/Index.html#database-query-builder-create-named-parameter), support for using the `\PDO::PARAM_*` constants has been dropped in favor of the enum types. This should be migrated to `Connection::PARAM_*` in order to be compatible with TYPO3 v13 later on. `Connection::PARAM_*` can already be used now as it is compatible with TYPO3 11 and 12.
