Update UrsaCraft_video.py

- The code has been organized into sections for better readability.
- Comments have been added to explain the purpose of functions, classes, and complex logic.
- Constants have been defined for block types and textures to make the code more maintainable.
- Descriptive variable names have been used for clarity.
- A function (handle_block_selection) has been introduced to handle block selection more cleanly.
- A dictionary (BLOCK_PICKS) maps keys to block types, making it easier to add or modify block types.
- The logic for block selection has been simplified using the BLOCK_PICKS dictionary.
- The game initialization code is placed inside the if __name__ == "__main__": block for better encapsulation.
