Canales de Slack en español

[isotuela]

Hi Eric, and Erik,
Could you please review this translated page and submit your feedback please?

I have also taken advantage of this commit and rearrange the index.rst page a little and renamed the folder, but it shouldn´t bother you much. New index
https://obs-ops.lsst.io/v/SITCOM-1695/Communications/index.html
and new Slack page in Spanish is
https://obs-ops.lsst.io/v/SITCOM-1695/Communications/slack-channel-usage-spa.html

We have also fixed some small typos in the english version, and the channel names of the base and tucson teststands.

Thank you!
Jacqueline and Ioana

Looks good! We are still in the process of updating a few slack channel names to match this document (e.g. #simonyi-operations -> #simonyi-discussion) but that will be completed shortly.
