Auto merge of #95096 - GuillaumeGomez:rm-header-fn-field, r=camelid

Remove header field from clean::Function

Fixes https://github.com/rust-lang/rust/issues/89673.

This is another take on https://github.com/rust-lang/rust/issues/89673 (compared to https://github.com/rust-lang/rust/pull/91217) but very different on the approach: I moved the header call in one place but still require to have the `clean::Item` so I can use the `DefId` to get what is missing.
