fix: adding support for other data types in orjson_dumps
Part of https://github.com/huggingface/datasets-server/issues/1443
Currently, we have 105 cache records with error types like:

```
  'Type is not JSON serializable: Timedelta',
  'Type is not JSON serializable: Timestamp',
  'Type is not JSON serializable: datetime.timedelta',
  'Type is not JSON serializable: numpy.int64',
  'Type is not JSON serializable: numpy.ndarray'
```

The problem is at https://github.com/huggingface/datasets-server/blob/main/libs/libcommon/src/libcommon/utils.py#L120 trying to serialize the values.

After this PR, I will force refresh the affected splits (most of them are for `split-first-rows-from-streaming`)

Also there is an error for "split-descriptive-statistics":

`"Dict key must be str"
`
This was due to non-string keys in ClassLabels like ints. After this PR, I will force refresh the affected splits (49 records)
