fix: removes polyfills intended to fix issues with older browsers.

[sebastianthulin]

Polyfill	Needed?	Notes
NodeList.prototype.forEach	Only for IE11	Remove unless you support IE11
Array.prototype.forEach	❌ Not needed	Safe to remove
Object.prototype.forEach	❌ Bad practice	Never do this, use Object.entries() etc.
