Translations of xarray core project website

What is your issue?

From @steppi in https://github.com/xarray-contrib/xarray.dev/issues/673

Hi xarray team,

With support from the CZI Scientific Python Community and Communications Infrastructure grant, Quansight Labs is able to offer assistance with developing and publishing translations of the brochure websites for the Scientific Python Core Project. You may have seen that translations into some languages are already available for numpy.org, with a version switcher in the top right corner; we're offering to help core projects integrate something similar into their websites. Our aim is to accomplish this in a way that requires minimal effort from the core project maintainers.

I've been tasked with setting up the software infrastructure for translations, and am posting issues today to ask core project teams if they would like to participate. I've published an FAQ here: scientific-python-translations.github.io/faq, with more information. Please take a look and let me know if you have any questions. If you decide to participate, I can begin setting up the translation infrastructure, which will require no work or input from maintainer teams (See here in the FAQ for more details on the process).

Start by reading the linked FAQ and the referenced xarray-contrib/xarray.dev issue to understand the proposed translation infrastructure and maintainer expectations. No repository file or test is identified; completion would require deciding whether xarray should participate and coordinating the website translation setup.
