Remove references to Unobtrusive Javascript in Rails 7.x getting started guide

[sockbot]

Steps to reproduce

In the getting started guide for Rails 7.0.0, there are references to Unobtrusive Javascript that are deprecated now that UJS has been replaced by Hotwire Turbo in Rails 7. These references include sample code that does not work with Rails 7 because UJS is not installed.

Expected behavior

The getting started guide should only have code samples and references that are relevant and functional in a new Rails 7 installation. All code samples and references that refer to UJS should be replaced with their Hotwire Turbo equivalents.

Actual behavior

The getting started guide should not have references or code samples that depend on UJS. Specifically, s.7.5. Deleting an Article sample code does not make a DELETE request, nor does the UJS confirmation dialog appear.

System configuration

7.0.0
