Add BotQ and KQL query documentation updates

Added an example JSON payload in `botmessage.md` for sending messages to the BotQ queue with parameters like `Count`, `Delay`, and `ThinkTime`. Updated `kql-queries.md` with a new KQL query example for analyzing game-related metrics (`codebreaker.game_moves`) and rendering a time chart. Expanded guidance on using Application Insights for metrics, logs, and custom dimensions.
