Added link of Computer Science Roadmap

[syedmouaazfarrukh]

Hi @PKUFlyingPig,

I came across your repository Self-learning-Computer-Science and found it to be a valuable resource for CS enthusiasts.

While browsing through the repository, I noticed that it was missing links to any structured guides such as the famous "Computer Science Roadmap". I took the initiative to submit a "Pull Request" adding it in "Great Resources" section.

Thank you for your time and effort in maintaining this valuable resource :)

Best,
Mouaaz

Thanks for your contribution. In fact, this repository is somewhat outdated, and I maintained a more updated and complete repository here.
