[🐛 Bug]: DevTools Functionality is Broken for Firefox 97 in Java

See original GitHub issue

What happened?

Firefox now requires an empty origin header for websockets, and Netty sends one by default: https://github.com/netty/netty/issues/9673

How can we reproduce the issue?

FirefoxDriver driver = new FirefoxDriver();
DevTools devTools = driver.getDevTools();

Relevant log output
