Inadvertent code block

There appears to be an accidental code block in the README.md:

https://github.com/CopilotKit/presentation-demo/blame/f594813c84555473bbf1c1f136e88c69bb53d1a2/README.md#L43-L52

Someone may have copilot and inadvertently auto-completed the trailing backticks on multiple commits, leading to a code block.
