[DOCUMENTATION] Refactored the readme file and added common cuDNN library issues

[patterns-complexity]

• I tried to make the documentation more streamlined
• I added an issue to common issues about missing cuDNN libraries, a few of my friends have stumbled upon it, me included, it took a while to understand where to get them from
• I added info on how to set up a vritual evironment with venv

For some reason GitHub is complaining about my email being different between the gpg signature and the account email. I realized I used my professional email for my signature but didn't have that email added to my account. I just now added the email but it didn't change the unverified warning 🤔 . I tried force-re-pushing of the same code and didn't help.
