[Bug] TYPO3 12: Collecting response message

[3l73]

The extension uses the class \Crossmedia\Fourallportal\Response\CollectingResponse handle the output in CLI and backend context.

The class itself is an inheritance of \Symfony\Component\Console\Command\Command which does not makes sense, since it is not an command and used only to collect message data.

The class should implement the interface \TYPO3\CMS\Core\Collection\CollectionInterface and remove the dependency to \Symfony\Component\Console\Command\Command.

Additionally, a method add(string ...$line): void should be added and replace the method setDescription(string $description).

The output within a command or controller can be done by walking threw the Collection.

Implementing the interface \Stringable would allow to concat the lines into a single string.
