Task search function on hub not working correctly
When I want to look at all datasets of the category: `speech-processing`  *i.e.* https://huggingface.co/datasets?task_categories=task_categories:speech-processing&sort=downloads , then the following dataset doesn't show up for some reason:

- https://huggingface.co/datasets/speech_commands

even thought it's task tags seem correct: 
https://raw.githubusercontent.com/huggingface/datasets/master/datasets/speech_commands/README.md
known issue due to https://github.com/huggingface/datasets/pull/2362 (and [internal](https://github.com/huggingface/moon-landing/issues/946)) , will be solved soon hmm actually i have no recollection of why I said that Because it has dots in some YAML keys, it can't be parsed and indexed by the back-end
