Scriptlets: inject quoted arguments without quotes

[chrmod]

This is required for scriptlets like:

www.youtube.com##+js(rpnt, script, /(\(function serverContract\(\))/, '/*start*/(function(){const e={apply:(e,a,r)=>{if(Array.isArray(r)){const e=r[0];(e.adPlacements||e.adSlots||e.adBreakHeartbeatParams||e.playerResponse)&&(r=[{}])}return Reflect.apply(e,a,r)}};Object.getOwnPropertyNames=new Proxy(Object.getOwnPropertyNames,e);let t=function(){document.querySelectorAll("script").forEach(e=>{e.textContent=e.textContent.replace(/\/\*start\*\/(.*)\/\*end\*\//g,"")})};"loading"!==document.readyState?t():document.addEventListener("DOMContentLoaded",t)}());/*end*/ $1')

The last argument is quoted but should be used without the quotes.
