Minor: 'Cargo doc' fix trivial lint errors.

[martinfrances107]

There are some stale references in the docs. When running cargo doc these are hidden as the user is inundated by a repeating trivial warning :-

warning: redundant explicit link target
  --> geo/src/algorithm/translate.rs:11:23
   |
11 |     /// [`AffineOps`](crate::AffineOps) trait.
   |          -----------  ^^^^^^^^^^^^^^^^ explicit target is redundant

As a first step I just want to clear these.
