🚀 Feature: Change the turtle's dialogue for each exercise

[SanjnaT41756]

Right now, the turtle's dialogue box only says one thing. We want to change this so it displays a randomized statement with every new exercise.

Proposed Solution

• there are different turtle svg sprites that come with the different texts
• change the prop in Turtle.tsx to take in a number rather than a string
• change the labelling of the different turtles within const turtleIDs: TurtleData from strings to numbers
• In LessonSide.tsx, pass in a random number (within the range as defined in Turtle.tsx) in the call to <Turtle/>

• 👋 I may be able to implement this update request
