rustdoc: remove unused CSS .content .item-list

[notriddle]

When these rules were added in 4fd061c (yeah, that's the very first commit of rustdoc_ng), .item-list was a <ul>, and this would override the default style for that tag.

In c1b1d68, it was changed to use a <div> tag, so these rules are both no-ops.

Is https://github.com/rust-lang/rust/actions/runs/3199349362/jobs/5225001335#step:25:4065 an intermittent test failure? @GuillaumeGomez I can't reproduce the fail locally.

[GuillaumeGomez]

Seems very unlikely since the DOM is fully loaded before this check is performed. How strange... Let's retry and if the CI pass, I'll add a mental note to check what happened.

[notriddle]

@GuillaumeGomez It passed.

[GuillaumeGomez]

I commented about it in #93784. Let's move forward for the current one.

@bors r+ rollup
