feat: replace survey with huh

[marwanhawari]

• require go v1.21
• add testify and gomonkey testing libraries
• replace unmaintained survey UI library with charmbracelet/huh UI library

Waiting for a max height feature for the Select component before I fully transition to huh. Opened an issue here:

Closing for now, as this was experimental. See this discussion for reasons why I wanted to try this.
