Prevent UA Client hints

[scoricov]

Hello,

This proposal is already implemented in Chrome: https://wicg.github.io/ua-client-hints/#intro
Example:

SEC-CH-UA: ".Not/A)Brand";v="99", "Google Chrome";v="103", "Chromium";v="103"
SEC-CH-UA-MOBILE: ?0
SEC-CH-UA-PLATFORM: "macOS"

This means the true UA and platform information leaks aside from the UA header which this extension is meant to control.

Solution for Chrome:

var settings = new CefSettings(); settings.CefCommandLineArgs.Add("disable-features", "UserAgentClientHint"); Cef.InitializeAsync(settings); 

Would it be possible to include it in the extension's code?

The next release will delete all "sec-ch-" headers;

Wouldn't deleting it altogether look suspicious as well?
Setting it to the latest version of Chrome (most used Browser) on Windows (most used OS) should be less conspicuous.

In the new implementation, the extension exposes the correct values instead of deleting them when the "navigator.userAgentData" object is present. If not, they get removed.
