fix: import runCLI off default export (fix #65)

[jacobq]

I believe this will fix #65

See also:

• [v25] - [ ERROR ] runJest: TypeError: runCLI is not a function jestjs/jest#9512 (comment)
• chore: convert jest-cli and jest-validate to esm jestjs/jest#8874 (comment)
• "Cannot read property 'runCLI' of undefined" with Jest 25.1.0 stryker-mutator/stryker-js#1983

Should also close #61 and #63

@jacobq thanks for temporarily publishing a package I can use until this pull request gets merged.

Running jest tests is working after replacing gulp-jest: ^4.0.3" with your package.

    "@babel/core": "^7.12.9",
    "@babel/preset-env": "^7.12.7",
    "@babel/preset-typescript": "^7.12.7",
    "babel-jest": "^26.6.3",
    "browser-sync": "^2.26.13",
    "esm": "^3.2.25",
    "gulp": "^4.0.2",
    "gulp-jest": "https://registry.npmjs.org/@jacobq/gulp-jest/-/gulp-jest-4.0.3-PR65.tgz",
    "gulp-sass": "^4.1.0",

    "jest-cli": "^26.6.3",
    "node-sass": "^5.0.0"
  }
