dependencies do not load PyQt5.QtWebKit

[mMerlin]

python Quark_Note_Taker/quark.py
Traceback (most recent call last):
  File "Quark_Note_Taker/quark.py", line 51, in <module>
    from mainwindow import MainWindow
  File "/home/phil/development/workspace/python/Quark_Note_Taker/mainwindow.py", line 53, in <module>
    from PyQt5.QtWebKit import *
ModuleNotFoundError: No module named 'PyQt5.QtWebKit'

Doing research, I found: https://stackoverflow.com/questions/50769024/modulenotfounderror-no-module-named-pyqt5-qtwebkit with a comment that says Use QtWebEngine, QtWebkit is deprecated. – eyllanesc

No idea what the api differences between those are.
