feat: Meta Quest Browser fix for ace editor zoom issue

[TiborUdvari]

This fixes #123.

I checked if it's the right browser, not to break anything for anyone else accidentally.

Nice idea – I'll have to test it out very soon on a Quest to see exactly what it's changing. Due to the size and singularly of the function etc – I'd rather it just get embedded directly within the monster index.html file, instead of external link. It can be called towards the end of settings rather than a listener on the DOMContentLoaded or use the listener, but call this function separately, incase others are needed in the future.

I did it like this because it modifies the ace editor css, since it's a hacky patch I though it would be best to only have it load when it's an Oculus Browser, that way it's 100% sure not to interfere with any other stuff

Notice checking the user agent

  if (!navigator.userAgent.includes("OculusBrowser")){
    return;
  }
