Improving Categorical Distribution Docs' (#16291) (#21707)
Summary:
**Closes:** Confusing documentation with distributions.Categorical about logits https://github.com/pytorch/pytorch/issues/16291
**Solution**: Changes documentation on the Categorical distribution from `log probabilities` to `event log-odds`. This makes should reduce confusion as raised by this issue, and is consistent with other distributions such as `torch.Binomial`.
More than happy to make any other changes if they fit :).
