Actually default-yes for installing dashboard

The instructions and the implementation didn't line up - we claimed
yes was default, but just hitting enter caused the value to be ""
which meant we didn't actually install it.

This is caused by using `IsConfirm`, where it doesn't set the default
as the default value, but rather uses the error value as `nil` if the
user agreed, and promptui.ErrAbort (which is `errors.New("")`) if the
user didn't.
