* Enhance Jest config error for `setupTestFrameworkScriptFile`

I wasn't aware of the fact that users of c-r-a could just define
`src/setupTests.js` and it would be configured with Jest - I nearly
ejected before I found a GitHub issue that confirmed this functionality.

I thought it might be a nice idea to add it to the error about Jest
config overrides to stop others ejecting when they don't need to.
