We need to wait for `huggingface_hub`'s next release to fix this (see https://github.com/huggingface/huggingface_hub/pull/1675; 409 error is currently ignored, hence the `KeyError`)

Also, we should be able to fix `test_push_dataset_dict_to_hub_overwrite_files` by inserting `gc.collect()` (to drop the  "reference" to an Arrow file) between the `load_dataset` calls to avoid the `PermissionError` (also reported in https://github.com/huggingface/datasets/issues/3139)

(Indeed, this can be addressed in subsequent PRs.)

I think this can be caused by collisions in temporary repository IDs because we create them in multiprocessing:
```python
with temporary_repo(f"{CI_HUB_USER}/test-{int(time.time() * 10e3)}") as ds_name:
```
This can also be caused when there is another issue that does not allow the creation of the repository, thus making it impossible to delete it.

This PR tries to fix this issue by increasing the precision of the number on the repository ID: `10e6` instead of `10e3`.
Additionally, this PR catches RepositoryNotFoundError.
