rustdoc: remove unused CSS `#main-content > table td`

This rule was added in 4e2c59a to benefit the module items table. However, the module items table stopped using table tags when 6020c79 switched us over to grid layout.

You can see when this one used to be triggered by visiting <https://doc.rust-lang.org/1.54.0/alloc/slice/index.html#structs-1> in a very narrow window, but it doesn't any more, because the module table is now rendered using `<div>` tags.
