Website translations - PR Review

Hi all,

As you may know, we have been working on translations for the website for a while, and we are happy to report that the translations for Portuguese (Brazilian), Spanish and Japanese are ready.

To pull them into the website, we need to merge a PR to create a language switcher and the initial language files: Add language switcher and translations by melissawm · Pull Request #617 · scipy/scipy.org · GitHub

If you have some time to spare, please take a look at the preview listed in that PR and let us know if you have any feedback.

Thank you!

Melissa
