errgroup: add reference to sync.WaitGroup

Add doc link to sync.WaitGroup in the package documentation.

Rationale:
The reference to sync.WaitGroup might be obvious to the authors of this
package, but it wasn't to me, so despites I had seen this package
multiple times I had never made the link to sync.WaitGroup. So when
playing with WaitGroup I was missing remembering about errgroup.
In hope this will help others as well as my future self.
