Option element: Missing value fallback implementation

[itutto]

Describe the bug
An <option> element's interface should return the textContent as fallback if no value attribute is present.

The current implementation returns an empty string in such cases.

happy-dom/packages/happy-dom/src/nodes/html-option-element/HTMLOptionElement.ts

Line 112 in 62e2920

return this.getAttributeNS(null, 'value') || '';

To Reproduce

The DOM content: <option id=test>Fallback value</option>
Expectation: expect(test.value === 'Fallback value'); // test.value will return ''

Expected behavior
This request is based on the specification:
https://html.spec.whatwg.org/multipage/form-elements.html#the-option-element

The value attribute provides a value for element. The value of an option element is the value of the value content attribute, if there is one, or, if there is not, the value of the element's text IDL attribute.
