Update roadmap tests and demos for 2024

Shift all roadmap tests and demo projects forward by one year to reflect planning for 2024. This update aligns all test dates, task timelines, and roadmap titles with the upcoming year, ensuring that sample roadmaps and test cases remain relevant and accurately represent future planning scenarios. Additionally, corrected a minor typo in a task name to maintain professionalism in demo outputs.

This change facilitates forward-looking development and testing practices, emphasizing readiness for future projects and the applicability of our roadmap visualization tools for the next calendar year.
