### About the icon

Scrum is one of the most popular agile frameworks in software development.

### Links and sources

https://www.scrumalliance.org/about-scrum
Found a scrum vector icon here: https://iconduck.com/icons/101723/scrum
There's also a svg file in this project (which isn't actively maintained anymore): https://github.com/vorillaz/devicons/blob/master/!SVG/scrum.svg

### Icon links and previews

### Additional information

I think a generic scrum icon should be added to devicon (instead of the Scrum Alliance icon).
