feat: support Angular 13 in CJS mode (#1122)

BREAKING CHANGE
* **NodeJs** range version support now is `^12.20.0 || ^14.15.0 || >=16.10.0`
* Due to the introduction of **ESM package format** for Angular packages, several things are added to the **default preset** to handle `.mjs` files from **Angular ESM packages**:
  + `ng-jest-resolver` is introduced as a custom Jest resolver to resolve `.mjs` files.
  + `transformIgnorePatterns` is added to inform Jest to transform `.mjs` files.
  + `transform` is updated to include `.mjs` extension to transform to `CommonJS` codes.

If one has custom Jest config, please make sure to adjust Jest config for CJS mode as following:
```
// jest.config.js
module.exports = {
     // other config
     resolver: 'jest-preset-angular/build/resolvers/ng-jest-resolver.js',
     transformIgnorePatterns: ['node_modules/(?!@angular)'],
     transform: {
        '^.+\\.(ts|js|mjs|html|svg)$': 'jest-preset-angular',
     },
}
```
