fix: [#1418] Fix Object.{entries,key,values} on Storage

[motss]

Background

This fixes #1418.

L79-84 checks that if a property does not exist in proxy target it return undefined for the configuration of the property and Object.keys(window.sessionStorage, '<existent_property_key>') returns { configurable: true, /** truncated for brevity */ } on the browser (Tested on MS Edge 124).

happy-dom/packages/happy-dom/src/storage/StorageFactory.ts

Lines 78 to 92 in c29f36c

	getOwnPropertyDescriptor(storage: Storage, key: string): PropertyDescriptor {
	if (
	Storage.prototype.hasOwnProperty(key) ||
	storage[PropertySymbol.data][key] === undefined
	) {
	return;
	}
	return {
	value: storage[PropertySymbol.data][key],
	writable: true,
	enumerable: true,
	configurable: false
	};
	}
	});

Changes

1. Fix Object.{entries,keys,values}() throwing TypeError on Storage by setting { configurable: true } for all existent property in the Storage
2. Add tests for above changes
