feat: 🗣️ Multi languages support

[philippart-s]

A proposition to add the ability to have the resume in several languages without to duplicate the all code.

It's improvable but it's a first version 😉.

An example of the generated CV:

@philippart-s can you fix conflicts, please?

[philippart-s]

@nelsonmestevao done 😉

[nelsonmestevao]

@sharu725 feel free to merge it if you agree 💪

[nelsonmestevao]

@philippart-s can you rebase to adder to more recent update of the folder structure?

[sharu725]

This is nice @philippart-s but it isn't the standard used across the web.
I think the link https://online-cv.webjeda.com/fr should be used for French.

Renaming index-fr to fr will do that.

But I still think there should be an easier way for the end-users to configure another language. At the moment, they'll have to edit a bunch of pages like the layout page, print page, and the language page itself.

Something like this would be good - https://github.com/kurtsson/jekyll-multiple-languages-plugin

[philippart-s]

yes you're right, I've not tested the Jekyll plugin you mention.
I'll take a look 😉.

Fell free to close this PR if you think it's not a good idea.
