Update the screenshot in the section 8.4 of Getting Started with Rails [ci skip]

[Angy-h]

Motivation / Background

I've been following the getting started guide. Upon reaching the end of section 8.4, I noticed several differences between the output displayed in the guide's screenshot and what appeared on my computer (rails version: Rails 7.1.2, ruby version: ruby 3.2.2):

• The positioning of "Edit/Back" differs.
• While the guide provides an explanation for "Destroy," it doesn't offer one for "Back."
• My output lacked the "Title:" and "Text:" elements.
• The text "Rails is Awesome!" appeared larger due to the h1 tag.

I would like to update the existing screenshot.
