Change all documentation code examples to CJS when clicking on CJS for one

### Affected URL(s)

https://nodejs.org/api/url.html

### Description of the problem

When I click on CJS for the first code example of a page in the documentation, the later code examples are still ESM, forcing me to click on the slider for every single example. That is annoying. It would also be nice if my choice could be remembered so I never have to think about that again.
