We no longer only allow coverage overrides, hence, I've also updated the wording here!

On a similar note, I've noticed that a few people would like an option to easily ignore certain files when running tests as mentioned in this StackOverflow post.

@iansu @amyrlam what do you think about including testPathIgnorePatterns in the override options? Happy to raise a PR for it.

The [default configuration](https://github.com/facebook/create-react-app/blob/master/packages/react-scripts/scripts/utils/createJestConfig.js) that Create React App uses for Jest can be overridden by adding any of the following supported keys to a Jest config in your package.json.

Supported overrides:

- [`clearMocks`](https://jestjs.io/docs/en/configuration.html#clearmocks-boolean)
- [`collectCoverageFrom`](https://jestjs.io/docs/en/configuration.html#collectcoveragefrom-array)
- [`coveragePathIgnorePatterns`](https://jestjs.io/docs/en/configuration#coveragepathignorepatterns-arraystring)
