Dead links to docs (borrowcheck)

[jdupak]

In https://rustc-dev-guide.rust-lang.org/borrow_check.html all the links to some subpaths of https://doc.rust-lang.org/nightly/nightly-rustc/rustc_borrowck/ are dead.

There was an issue generating the docs. It should be fixed tomorrow via rust-lang/rust#117535.

Thank you both for reporting and providing the context!
Closing as there's nothing to do here.
