Port to pyqt5 or remove from focal archive

[Rik Mills]

Since Qt4Webkit support was dropped from python-qt4 in Bionic, this tool fails to start.

Traceback (most recent call last):
  File "/usr/bin/code-of-conduct-signing-assistant", line 32, in <module>
    import codeOfConductSigningAssistant as app
  File "/usr/share/code-of-conduct-signing-assistant/codeOfConductSigningAssistant/codeOfConductSigningAssistant.py", line 30, in <module>
    from PyQt4 import QtCore, QtGui, QtWebKit, QtNetwork
ImportError: cannot import name 'QtWebKit

Unless ported to pyqt5, this should be removed from focal archive as part of the Qt4 removal.

It is notable that no bugs reporting the failure to start in bionic have been reported, so it looks like the usage and usefulness of this tool is near to nil
