[tensorflow-addons] Fix Build & Hardcoded References to Python 3.8

tensorflow-addons was failing to build due to the outdated version of
Pyinstaller provided by the base-builder image. This upgrades
Pyinstaller to the latest version known to work, and updates a hardcoded
path pointing to Python 3.8 now that the base-builder image installs
Python 3.10.
