[Up for grabs] Angular Resources

[sophiabrandt]

There is a file called Angular.md where some kind soul has collected resources related to the JavaScript framework.
The file is not part of the TOC in the Readme.md file.

I suggest adding a link to the file with a short description in README.md, like so:

- [**Algorithms & Data Structures**](AlgorithmsDataStructures.md): Resources for tackling algorithms.

- [**Articles**](DevelopmentArticles.md): General articles page on web development.

For more info, see the guide.
