Multilingual per post instead of per site?

[JOduMonT]

Maybe I'm a simplistic fool,
but what if we pass the constant language string at the page level instead of the site config level
export const language: string = getSiteConfig('language', 'en')
and add language as an option on each post, so that would allow people to easily exploit the multilingual aspect of this starter-kit.
By default, English could be defined in absence of configuration, so it would not even both unaware users of that new possiblity.
