[Add languages offered]

Is your feature request related to a problem? Please describe.
This is a feature request. I'd like to see awesome certificates multilingual. As many of the certificates/courses on the list already are offered in multiple different languages.

Describe the solution you'd like
I'd like to see a new column for languages offered on each course as follows:

Course Name	Course Provider	Level	Hour(s)	Reward	Languages
					🇨🇳CN, 🇫🇷FR, Etc.

Also it would be great if the readme.md is translated for each local language to make it more accessible and inclusive for everyone.
