since we are in the shortenedRecursiveExport method, I think its acceptable to shorten these arrays more agressively.

before this PR running phpunit on a dataprovider with lots of elements resulted in a big wall-of-text description like

PHPUnit 11.2.2 by Sebastian Bergmann and contributors.

Runtime:       PHP 8.3.8
Configuration: /Users/staabm/workspace/exporter/phpunit.xml

................................................................. 65 / 74 ( 87%)
