fix(tools): update migrate-converged generator to add node field to package.json exports map

[TristanWatanabe]

Changes:

• updates migrate-converged-pkg workspace generator to add a node field within v9 package's export maps to address issue where native ESM doesn't work in a node environment.

Issue and Solution Story:

Before:

See test.mjs file below which uses ESM import syntax:

//test.mjs file
import { getSlots } from '@fluentui/react-utilities';

// eslint-disable-next-line no-console
console.log(getSlots);

Running node test.mjs in the terminal results in error below:

After:

Adding node to the package.json's exports map which points to the commonjs output fixes this:

  // @fluentui/react-utilities package.json file
  "exports": {
    ".": {
      "types": "./dist/index.d.ts",
      "node": "./lib-commonjs/index.js",
      "import": "./lib/index.js",
      "require": "./lib-commonjs/index.js"
    },

Now when running node test.mjs in the terminal, expected result is outputted:
