Don't add a tag on the Hub on release
Datasets with no namespace on the Hub have tags to redirect to the version of datasets where they come from.
I’m about to remove them all because I think it looks bad/unexpected in the UI and it’s not actually useful

Therefore I'm also disabling tagging.

Note that the CI job will be completely removed in https://github.com/huggingface/datasets/pull/4974 anyway
