docs: replace torch.distributed.run by torchrun (#27528)
* docs: replace torch.distributed.run by torchrun `transformers` now officially support pytorch >= 1.10. The entrypoint `torchrun`` is present from 1.10 onwards.

For the duration of this section let's assume that you have 2 nodes with 8 gpus each. And you can reach the first node with `ssh hostname1` and second node with `ssh hostname2`, and both must be able to reach each other via ssh locally without a password. Of course, you will need to rename these host (node) names to the actual host names you are working with.
