Use Bubble Tea for interactive mode UX (#100)

* Use Bubble Tea models for the interactive questionnaires

Co-authored-by: Gavin <[email protected]>

* Improve Ctrl+C handling when asking a single instance ID

* Update confirmation message to indicate whether user can change their answers (available only in interactive mode)

* New method for asserting array equivalence, regardless of item order, whitespace, or string case

This fixes flakiness in two tests: TestAskUserTags_WithDefault and TestAskSecurityGroups_Success
