Translate the website to multiple languages

[nihey]

I was trying to look onto some of the options on translating SWIC to other languages other than English, and as of now, I've found out the probable best way to do it would be to move the project to a Gatsby Base, generate the .po files for each language and proceed from that.

This would probably also lead us to some improvements on SEO and maintainability.

I can work on a POC for it to estimate the amount of work it would take us.
