Deprecate commands from the transformers-cli that are in the hf-cli
Commands that are both in the `transformers-cli` and in the `huggingface-cli` are deprecated here and will be quickly removed.

I'm voting for deprecating them and not removing them even though better ways exist as I suspect some users to use the `transformers-cli` in bash scripts to automatically upload models to the hub.

Context from @julien-c:

my reason for removing (still keeping a descriptive error obviously) rather than deprecating is that I'd love to know if people actually use those (and if they do, do they use them in scripts or manually)

But I will defer to the great transformers-maintainers as the final decision 💖<|||||>sounds good to me!
