Enhance project cloning and initialization process

- Updated CloneCommand to support multiple place IDs, allowing the creation of multi-place projects with individual project files for each place.
- Refactored the initialization logic in InitCommand to streamline project setup and ensure proper handling of project templates.
- Added a new function to fetch place names from the Roblox API, improving the user experience during project creation.
- Updated TODO.txt with a new entry for fixing the luau-lsp sourcemap generator command.
