We need to update https://github.com/nightwatchjs/selenium-server-jar-download/blob/main/package.json#L8 to match the latest selenium server, 4.18 at time of raising this.

I can take care of this, just need to update the version in the package json and do some tests for everything to continue working correctly, or to eventually adapt some code if is not working

Hopefully you won't have to do much more than update the package.json. If it does break please update so I can help
