OSINT VM Updates

Things change quickly. Today, I made the following updates to the OSINT Virtual Machine:

Modified linux.txt, linux.sh, and updates.sh to update the "sudo" pip installation options. This resolves some path issues caused by my previous "update".

Modified linux.txt, linux.sh, reddit.sh, and updates.sh to update the installation, execution, and update process for 'Bulk Downloader For Reddit'. Note that this utility requires Python 3.9 and the automated script will not work until Ubuntu defaults to Python 3.9.

Overall, use the text files and scripts provided within the link from your book. If your recent build is not functioning properly, rebuild with the new files.
