Broken [src] links in documentation

[Seeker14491]

The [src] link on these pages is broken:
https://doc.rust-lang.org/nightly/std/collections/struct.BTreeMap.html
https://doc.rust-lang.org/nightly/std/collections/struct.BTreeSet.html
https://doc.rust-lang.org/nightly/std/collections/struct.BinaryHeap.html
https://doc.rust-lang.org/nightly/std/collections/struct.LinkedList.html
https://doc.rust-lang.org/nightly/std/collections/struct.VecDeque.html

The links are also broken in the stable docs version of these pages.

I think this should be fixed by #30149 (haven't verified yet).

The links wrongly point to core_collections instead of collections because the crate is linked in std like extern crate collections as core_collections;

I've built the docs locally and the issue somehow persists.
