Add Git - the simple guide to the prerequisite section

[rmrgh]

git - the simple guide is a good resource because provide a lot of information of the git workflow in a few minutes and it's available in 16 languages, good for someone that maybe have some difficult with English.

@ramirio

thank you for your help! 🙏

Could you also make more two things?

• Bump our Curriculum Version to 1.2.1 here, because you're adding a resource in our file.

• Add a little explanation in our CHANGELOG file, saying what you're doing. More explanations about CHANGELOG files here. The text will be something like this:

  [1.2.1] 2015-10-11
  
  ### Added
  - Article Git - the simple guide to the prerequisite section.
