Rollup merge of rust-lang#109093 - Dante-Broggi:patch-2, r=joshtriplett

add `#[doc(alias="flatmap")]` to `Option::and_then` I keep forgetting that rust calls this `and_then` and trying to search for `flatmap`. `and_then`'s docs even mention "Some languages call this operation flatmap", but it doesn't show up as a result in the search at `https://doc.rust-lang.org/std/?search=flatmap`
