this.util.TextEncoder is not a constructor while importing a webpack bundled file containing Human in Node

[Smruti-AT]

Issue Description
I have imported Human in a file to do some ml stuff. Then I bundled the file using webpack. Now when I'm trying to import the bundled file into another file, I get this error:

Steps to Reproduce

Clone https://github.com/Smruti-AT/test_bundle.git (Sample code)
Run npm install inside /ml
Run npx webpack inside /ml
Run node index.js inside /app

Environment

Human library version? 3.3.4
Built-in demo or custom code? Custom code.
Type of module used (e.g. js, esm, esm-nobundle)? esm
TensorFlow/JS version (if not using bundled module)? 4.22.0
Browser or NodeJS and version (e.g. NodeJS 14.15 or Chrome 89)? NodeJS v20
OS and Hardware platform (e.g. Windows 10, Ubuntu Linux on x64, Android 10)? Ubuntu 20
Packager (if any) (e.g, webpack, rollup, parcel, esbuild, etc.)? webpack 5

I have also tried to do polyfills for the util package as suggested by StackOverflow but still got the same error.
