Add language Spanish (ES_es)

I upload the translated Spanish translation file.

I'm going to mark this as draft for now. I'd like to focus on the English translations first and then once we're happy with that, we can start to implement others. But we'll keep this here!

Perfect! When you want to translate it you can let me know and I'll check it!

Sorry to be a huge pain, @soymgomez, but I've just merged in https://github.com/cachethq/core/pull/162 which converts Cachet's translations files to use short keys. I appreciate this is a pain, but:

1. @danjohnson95 took the time to localize all strings within Cachet.
2. Using short keys allows us to provide context to individual translations throughout the application.

I'd really appreciate your support in updating your PR 🫶
