I played around with this PR a bit (as I think docs are quite important) --
thanks @Rafferty97
I found I could fix the link in the docs like this:
```rust
#[doc = "Return a [`ScalarUDF`](datafusion_expr::ScalarUDF) for [`"]
#[doc = stringify!($UDF)]
#[doc = "`]"]
pub fn $NAME() -> std::sync::Arc<datafusion_expr::ScalarUDF> {
```
However, then I got warning about documenting private items. So I chose to
just skip the links
```
warning: public documentation for `cardinality_udf` links to private item
`Cardinality`
--> datafusion/functions-nested/src/macros.rs:94:21

94 | #[doc = concat!("ScalarFunction that returns a
[`ScalarUDF`](datafusion_expr::ScalarUDF) for [`", stringify!($UDF), "`]")]
