Update welcome_to_llmware_windows.sh

This pull request introduces a Bash script for setting up the LLMWare environment and running selected examples. The script handles the installation of core and optional dependencies, moves selected example scripts to the root directory for easy execution, and provides informative feedback throughout the process. It also includes basic error handling to ensure smooth execution.
