Pip Update 2023

I finally made some time to update the Pip tool download link based on some folks kindly reaching out regarding a broken download link. A new link is listed below and I also took a little time to fix a few more bugs as well! :)

- PySide2 Support for Maya 2018+
- Fixed a bug with the tutorial throwing errors in niche cases where the tool was excited at specific times.
- Minor code cleanup and refactor.
