Implement localization for `./web`

[ZibanPirate]

As a user, I should easily switch to either En, Ar, or Fr on any link in dzcode.io to Social Media, and see content in the respective language.

Tasks:

• [x] Add language changing option to All dzcode.io pages ( #269 )
• [x] Add RTL support ( #270 )
• [x] Handle Urls in multi-language. (#396 and #390 )
• [x] refactor data folder to support multi-language content (#403 )
• [x] translate the static website content ./web (#420 )
• [x] #465

Feature Branch : feat/localization Feature PR : #275
