Add a link to a 250 question quiz on Git

[SaravananSubramanian]

Changes

• Adds a new link to a roughly 250 question online quiz (https://saravanansubramanian.com/git-quiz/) to help aid in the understanding of the basics of Git version control. This quiz tests your knowledge on topics such as basic Git commands, branching strategies, merging, conflict resolution, remote repositories, patches, submodules, work trees, subtrees, LFS, configuration, and collaborative development best practices.

Context

I created one for my own use and for my colleagues recently, and now I feel it can be useful for others.

If git-scm.com was a place to collect all the things Git, I would be in favor of this PR.

However, there is just too much of Git-related stuff, and it looks as if there are more actively-maintained aggregator sites than this here repository. The best place might be the Git RevNews.

Therefore, I would be in favor of closing this PR without merging it.

i think i agree with @dscho on this one. tbh, maintaining a curated list of links here is very hard. new links appear. old links die or get updated...

maybe something like https://github.com/dictcp/awesome-git is easier.

it's also very easy to find tutorials through google or Reddit or any developer forum at this moment tbh...
