Feature Request: Language toggle button for Minimal Blog theme

[sgc109]

Hi, I just have an idea for the Gatsby Starter: Minimal Blog.
How about adding language toggle button on the right-top position(next to light/dark mode button)?

I think there are quite a lot of people, including me, who want to support multi language in their own blog.
For example, if I toggle button, current language configuration just change from Korean to English.
If I click the button on the post list page, then only posts with English version appear.
If I click on the post detail page, if the post doesn't have English version, then go back to the list page.

Although I know this is the "minimal" blog theme, I think it can't be more perfect if it supports this kind of feature in this incredibly beautiful and simple theme. 🙏🏻
