fix!: update composer.json specifics

See merge request !17

In this commit, the PHPStan version was updated in .phive/phars.xml. Several refactors were done to
the DemoData.php file and some other related files:

- Updated type hints in the DemoData.php class.
- Removed suppression of PHPStan warnings in the media.php
- Employed `array_map` in data processing within DemoData.php
- Updated PHPStan version to enforce these changes.
- Introduced the PHP 8 match expression in the DemoDataParser class.
- Fixed potential bug in the `processEvents` method inside the EventParser class.

This refactoring process was aimed at improving the integrity and readability of the code while
updating some parts of the codebase to better align with modern PHP practices.

connection. The required PHP version and the version of quiqqer/core have also been defined,
ensuring expected behavior even after potential updates or changes.
