Summary

https://github.com/jevakallio/jest-clean-console-reporter documents a pattern of doing

    // Overriding config.reporters wipes out default reporters, so
    // we need to restore the summary reporter
    "@jest/reporters/build/SummaryReporter",

This won't work in Jest 27 due to #9921.

$ node -p 'require("@jest/reporters/build/SummaryReporter")'

internal/modules/cjs/loader.js:438
      throw e;
      ^

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './build/SummaryReporter' is not defined by "exports" in /Users/simen/repos/jest/node_modules/@jest/reporters/package.json

    at Script.runInThisContext (vm.js:133:18) {
  code: 'ERR_PACKAGE_PATH_NOT_EXPORTED'
}

This change allows one to do

const {SummaryReporter} = require('@jest/reporters');

// this absolute path can be passed to `require`
const path = SummaryReporter.filepath;

/cc @jevakallio

Test plan

Tested in the shell 馃槄

$ node -p 'require("@jest/reporters").SummaryReporter.filename'

/Users/simen/repos/jest/packages/jest-reporters/build/SummaryReporter.js
$ node -p 'require(require("@jest/reporters").SummaryReporter.filename)'

{
  default: [class SummaryReporter extends BaseReporter] {
    filename: '/Users/simen/repos/jest/packages/jest-reporters/build/SummaryReporter.js'
  }
}

And since we handle default "export" from CJS, this should work fine 馃憤
