What is done

Implemented ignoreDiffPixelCount optional param to assertView command.
With there params, it would be possible to ignore 2-5 pixel image diffs, which are hard to get rid of

Example:

it('example', async ({browser}) => {
    // ignores up to 5 diff pixels
    await browser.assertView('some-state', 'some-selector', {ignoreDiffPixelCount: 5});

    // ignores up to 5% diff pixels
    await browser.assertView('other-state', 'other-selector', {ignoreDiffPixelCount: "5%"});
});

Changed this method's params to be a single object. This would be passed into html-reporter

Turns out, you can do such things in typescript.
Using `${number}%` | number directly, without extra type, because this way you can get clear understanding about what type this field wants value to be:

* @remarks
* Usefull, when you have 2-5 different pixels you can't get rid of using `tolerance` and `antialiasingTolerance`.

меня здесь смущает связка "get rid of using tolerance". Выше писал как можно перефразировать
