Description

https://github.com/AdguardTeam/Scriptlets/blob/master/wiki/about-trusted-scriptlets.md#-%EF%B8%8F-trusted-replace-fetch-response

Recently, YouTube started neutralizing adblockers so they would stop working on their website.
But, @AdamWr found a method blocking the anti-adblock script using trusted-replace-fetch-response trusted scriptlet of AdGuard.
However, in uBO, a trusted scriptlet working like AdGuard's trusted-replace-fetch-response does not exist.
