Spanish translation of the file debugging.mdx
# What does this PR do?

Fixes #[15947](https://github.com/huggingface/transformers/issues/15947)
Adds the Spanish version of [debugging.mdx](https://github.com/huggingface/transformers/blob/master/docs/source/en/debugging.mdx) to [transformers/docs/source/es](https://github.com/huggingface/transformers/tree/main/docs/source/es)

Also found one typo error in the original doc, so I fixed it also.

@omarespejel @osanseviero  @sgugger 
Can you just add the new file to the TOC of the Spanish doc? (in `transformers/docs/source/es/_toctree.yml`)<|||||>@sgugger like that is fine? Tried to mimic the eng TOC creating the same section "Rendimiento y escalabilidad"<|||||>_The documentation is not available anymore as the PR was closed or merged._<|||||>All good, thanks!
