Rollup merge of rust-lang#146242 - GuillaumeGomez:rustdoc-gui-scrape, r=lolbinarycat

Ensure that `--html-after-content` option is used to check `scrape_examples_ice` rustdoc GUI test

Follow-up of rust-lang#146091.

This test ensures that the spans are correctly handled when a "local source file" is not the first in the file list. To ensure it's actually what's tested, this test checks that the option is actually used by adding an element.
