errgroup: add reference to sync.WaitGroup

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

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.
