errors: fix package example
The example in example_test.go requires that the whole file be
displayed; the addition of ExampleAs meant that only the body of the
package example function was shown, rather than the surrounding context.
This change moves ExampleAs to the file wrap_test.go file, restoring the
package example to its former glory.
Update #31716
