Improve prevent-fetch — set response.ok to false if response.type is opaque

[AdamWr]

Steps to reproduce:

1. Add this rule:

example.org#%#//scriptlet('prevent-fetch', 'googlesyndication', '', 'opaque')

2, Go to - https://example.org/
3. In browser console run:

(async () => {
  try {
    const response = await fetch('https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js', {
      mode: 'no-cors'
    });
    if (response.ok) {
      alert('adblock');
    }
  } catch (error) {
    alert('adblock');
  }
})();

Alert is displayed, because response.ok is true, but without ad blocker is false.
Adding ok: { value: false; } to:

Scriptlets/src/helpers/noop-utils.ts

Lines 126 to 132 in 85b3346

	Object.defineProperties(response, {
	body: { value: null },
	status: { value: 0 },
	statusText: { value: '' },
	url: { value: '' },
	type: { value: responseType },
	});

should fixes it.

This issue - #394 (comment) could be also fixed.

I think that the problem is that website overrides Object.defineProperties which is used by prevent-fetch.
