Reporter options for Jest

Created by: jdelucaa

Is your proposal related to a problem?

CRA only supports overriding a few Jest options and reporters is not one of them. I know that I can add reporters via cli --reporters=my-reporter, the problem is that I would like to pass in some options to that, but reporter options are not available via cli (https://jestjs.io/docs/en/next/cli#--reporters).

I really don't want to eject my CRA setup, so i wish it was more flexible when it comes to Jest configurations.

Describe the solution you'd like

This is what I'd like to be able to do:

"reporters": [
  "default",
  ["./node_modules/jest-cucumber/dist/src/reporter", {
    "formatter": "json",
    "path": "./reports/test-report.json"
  }]
],

Describe alternatives you've considered

I could use something like craco, but it would be even nicer to have it (and other Jest configs) out of the box in CRA.
