Automatically convert cache_dir string to path in script

[ecarrenolozano]

This pull request updates the logging configuration, improves cache directory handling in the downloader, and updates the sandbox use case to use a new downloader adapter. The main changes focus on standardizing file paths and switching to a new download manager for improved functionality.

Logging configuration updates:

• Changed log file name in 04_workdir.yaml from my_saezapp_logger.log to app_go_logger.log for clearer identification.
• Removed the root logger configuration from 04_workdir.yaml to simplify logging setup.

Downloader improvements:

• Updated ontograph/downloader.py to ensure cache_dir is always a Path object, improving path handling and consistency.

Sandbox use case updates:

• Modified sandbox/use_case_downloaders.py to use the new DownloadManagerAdapter instead of PoochDownloaderAdapter, and standardized the cache directory path usage throughout the script. [1] [2]
