docs: Update clearCookie documentation for Playwright helper

[Hellosager]

Motivation/Description of the PR

Me and a co-worker were wondering why all cookies got deleted when calling Playwright helper clearCookie function with the cookie specified. After checking the source code, I saw the comment of this not beeing a feature in playwright.

I updated the broken link in the code comment and the documentation of the helper.

Applicable helpers:

• Playwright
• Puppeteer
• WebDriver
• REST
• FileHelper
• Appium
• TestCafe

Applicable plugins:

• allure
• autoDelay
• autoLogin
• customLocator
• pauseOnFail
• coverage

• selenoid
• stepByStepReport
• stepTimeout
• wdio
• subtitles

I guess you haven't run the npm run docs.

I guess you haven't run the npm run docs.

This is true, I thought it's just needed for new docs, not editing existing ones.
I checked out my repository and tried npm run docs on Kali now (after realizing windows isn't working) but it seems that it is only rolling back my changes to the current state of the docs.
Where do I have to do my changes so that npm run docs is keeping my changes or what else am I missing?
