Add is feedback enabled prop to box ai sidebar

[jankowiakdawid]

We're reading isFeedbackEnabled from the host app, and pass it to BoxAiContentAnswers.

This is an optional prop that is false by default. When true it enables Thumb Feedback Buttons in every answer that record if user consider the answer helpful.

Still work in progress, requires:

• bump of @box/box-ai-content-answers package
