Add ReactJS as skill

[caitmuenster]

It would be great to add ReactJS as a skill. Unfortunately, it looks like the skills come from the languages that GitHub lists in the repositories, and it doesn't seem to recognize JSX as a distinct language.

Some Mozilla projects that use React include:

• AMO frontend
• Firefox Dev Tools
• Mozilla Activate
• Common Voice
• Activity Stream (readme) (bugs)
• Firefox Screenshots (readme) (bugs)
• Treeherder

That would be a great addition! Unfortunately, it will be a bit tricky since GtiHub doesn't allow setting ReactJS as a language. One way for now is to add a "react" label to the project yaml file so that codetribute scans for these issues. The user will then be able to:

• see issues that have the "react" label when viewing a project
• click the "react" label to only see react issues for a project

Thoughts? Let me know if there was a particular project you wanted me to add that label.
