RoCrate Merge

In this issue, we want to handle the merge problem for RoCrate objects. This code is based on the latest update from reporter plugin [branch](https://github.com/BAMresearch/NFDI4IngModelValidationPlatform/tree/55-reporter-plugin-update-rohub-upload-issue) and Benchmarking package [branch](https://github.com/BAMresearch/NFDI4IngModelValidationPlatform/tree/47-creation-of-the-benchmarking-package)
