Add Reactions to Pull Requests, Issues, and Comments

GitHub has introduced Reactions to improve communication and reduce clutter in conversations around code, design, bugs, and new ideas. This feature allows users to express their feelings more efficiently by using specific emoji such as 👍, 👎, 😄, 😕, ❤, and 🎉, which are relevant to typical user interactions on the platform. Previously, including emoji in responses often led to long threads with little content, complicating discussions. The new Reactions feature is now available on all Issues and Pull Requests, and the GitHub team, led by Jake Boxer, is eager to see how the community will utilize this enhancement.
