Support jsx-runtime for jest babel transform

[wanglam]

This is a part of work about #205 .
I upgrade react-scripts to 4.0.1 version, and everything fine with npm run start / npm run build.
But when I run npm run test, the error occurs like this:

Here is the example project: craco-jsx-runtime-jest-bug, will get the same error.

Then I go to the react-scripts/config/jest/babelTransform.js, find we need runtime option to support jsx-runtime. So I create this pull request.

For old version babel-preset-react-app(I have checked this file), it's ok to pass same options, I just ignore version check.

Hi @wanglam

Thanks for the PR :)

Did you do anything else to make Jest works with react-script 4.0.1 and React 17?

I get the following error:

Thank you,

Hi @patricklafrance

No, I didn't do anything else to make Jest work with react-scripts 4.0.1 and React 17.

I confirmed If you create a new project based CRA(version 4.0.1) and run npm run test. Everything work fine, no error will be found.

Would you like to upload your project? Maybe we can check it together.

@wanglam I was running yarn jest instead of yarn test :(
