rustdoc-json: Add test for #[automatically_derived] attribute

[aDotInTheVoid]

Will fail CI due to freestrings/jsonpath#91, but I wrote the test and don't want to forget it.

We should look into fixing the freestrings impl, or moving to a different one, so we can test things like this. Zulip Disussion

still blocked on changing json path implementation. this is something i’d like to do, but low priority
