update AlecAivazis/survey to v2

[MarlonGamez]

Fixes #5114

Description
Bumps the version of https://github.com/AlecAivazis/survey to v2. The previously used version would allow for a situation where we dereference a nil pointer in skaffold init

The situation that would cause this is when the user is matching builders to images interactively, if they tried to filter by typing, but their search had no results and they hit enter anyway, it would effectively select nothing and return that value.

With the updated package, if the search returns nothing and they hit enter, nothing will happen. They will have to make a valid choice before moving on.
