Rollup merge of #129796 - GuillaumeGomez:unify-code-examples, r=notriddle

Unify scraped examples with other code examples

Fixes #129763.

This first PR both fixes #129763 but also unifies buttons display for code examples:

![image](https://github.com/user-attachments/assets/c8475945-dcc3-4c25-8d7d-1659f85301c8)

You can test it [here](https://rustdoc.crud.net/imperio/unify-code-examples/doc/scrape_examples/fn.test.html) and [here](https://rustdoc.crud.net/imperio/unify-code-examples/doc/scrape_examples/fn.test_many.html).

I'm planning to send a follow-up to make the buttons generated in JS directly (or I can do it in this PR directly if you prefer).
