Misc #17842: Example incorrect in documentation for Hash#dig

----------------------------------------
In the current examples for Hash#dig, we have:
```
h = {foo: {bar: {baz: 2}}}
h.dig(:foo) # => {:bar=>{:baz=>2}}
h.dig(:foo, :bar) # => {:bar=>{:baz=>2}} <-- incorrect return value
```

This should be:
```
h = {foo: {bar: {baz: 2}}}
h.dig(:foo) # => {:bar=>{:baz=>2}}
h.dig(:foo, :bar) # => {:baz=>2}
```

I have a pull request incoming to fix this on GitHub, but I can create a patch and post it here if that is better.
