fix increase_load_count
The docs for this PR live [here](https://moon-ci-docs.huggingface.co/docs/datasets/pr_7165). All of your documentation changes will be reflected on that endpoint. The docs are available until 30 days after the last update. I tested a few load_dataset and they do show up in download stats now Thanks for having noticed and fixed.
it was failing since 3.0 and therefore not updating download counts on HF or in our dashboard
