fixed sample code to open a new window or tab using ruby

Description

current sample code doesn't work, with this change user will be pointed to the right direction on how to open a new window or tab using ruby

Motivation and Context

I was trying to achieve this and following the sample code didn't work, after looking at other languages I figured it out, maybe some people won't do that I will think the feature is just not working in ruby

Types of changes

• Change to the site (I have double-checked the Netlify deployment, and my changes look good)
• Code example added (and I also added the example to all translated languages)
• Improved translation
• Added new translation (and I also added a notice to each document missing translation)

Checklist

• I have read the contributing document.
• I have used hugo to render the site/docs locally and I am sure it works.

Good catch, we changed the implementation of this and didn't update the documentation.
Can you update these lines in all 4 of the translation files?

(or if you are interested in being especially helpful write the code here so we can link to it in the docs? https://github.com/SeleniumHQ/seleniumhq.github.io/blob/trunk/examples/ruby/spec/interactions/windows_spec.rb)

Thank you so much for taking the extra step here!

A couple updates specific to how Hugo/Docsy need things formatted.
Also, I don't think we need to include any of the navigation things? Just the command to create the window/tab (and the assertion in the specs so when we run it in the CI we know it is working.
