Add example with external node modules

Bump jest version

I think these are the last versions that work properly with import statements:

{ 
    "@types/jest": "^26.0.0",
    "jest": "^26.0.0",
    "ts-jest": "^26.0.0"
}

If you bump this to v27 or higher you'll get:

Error [ERR_REQUIRE_ESM]: require() of ES Module ~/project/node_modules/wrap-ansi/index.js from ~/project/node_modules/jest-cli/node_modules/cliui/build/index.cjs not supported.
Instead change the require of index.js in ~/project/node_modules/jest-cli/node_modules/cliui/build/index.cjs to a dynamic import() which is available in all CommonJS modules.

error Command failed with exit code 1.

Do you know if there's a way to fix this?
