This PR introduces default launchpad assets for Guided Templates. It involves updates to the file structure, including the addition of a new directory named launchpad within the assets directory. This directory contains a subdirectory named slides, which stores assets associated with the launchpad carousel. Additionally, the generate_index.php script file has been refactored to accommodate the new subdirectory file structure for launchpad assets.

3. Navigate to Processes -> Guided Templates.
4. Run a guided template.
