deploy-on-aws: defusedxml.ElementTree does not expose Element/ElementTree types

[RafaelPinto]

Describe the bug

Post-processing scripts use ET.Element/ET.ElementTree type annotations from defusedxml.ElementTree, which doesn't expose those classes. All fixer scripts crash at import time.

Expected Behavior

Scripts should import and run without errors

Current Behavior

AttributeError: module 'defusedxml.ElementTree' has no attribute 'Element' on all 4 fixer scripts

Reproduction Steps

pip install defusedxml>=0.7.1 && python3 -c "import defusedxml.ElementTree as ET; print(ET.Element)"

Possible Solution

Add from xml.etree.ElementTree import Element, ElementTree and replace ET.Element/ET.ElementTree with direct imports
