Fix references to `ControlFlow` in docs

The `Iterator::for_each` method previously stated that it was not possible to use `break` and `continue` in it — this has been updated to acknowledge the stabilization of `ControlFlow`. Additionally, `ControlFlow` was referred to as `crate::ops::ControlFlow` which is not the correct path for an end user.
