Add ratings feature for Tidbits

[RobinNagpal]

1. We should ask for the ratings after we complete the tidbits
2. Tidbits rating should not be shown after completing each Tidbit, as it will be annoying. When do we show it? How do we configure it?

Approach 1: Limiting Frequency with Local Storage
For limiting the frequency of the rating modal, we can store the last shown timestamp in the localStorage and only show the modal when certain time has passed.

Approach 2: User Preferences for Feedback Timing
Allowing users to specify when they’d like to be prompted for feedback. We can provide options within our application settings where users choose their preference. Based on this preference, use similar logic as above to decide when to show the modal.
