Website translation about pymc-data-umbrella

[OriolAbril]

#154 started setting up the infrastructure for translations. We are working on the docs about how to translate now.

Anyone interested in trying can already go to https://www.transifex.com/pymc/data-umbrella-sprints-website and request to be added as a translator to get started.

The translations have only triggered the issue, they are perfectly fine. I would leave them there so when we fix those issues the website gets updated automatically

Pages that should not be translated (at least for now):

• about/intro_to_array_operations/notebook
• about/probabilistic_programming_with_pymc/notebook

Full context: there are some issues with the internationalization process of the website, so some pages need to be excluded from the translated website generation process for it to work. It would only make sense to translate these after we have managed to fix those.

Ia this the cause of #195? These resources are already translated for Spanish, should we unreview the translations?
