fix: sync correct Python stdlib implementation from main

Previous commit accidentally synced an older shell-based version.
This commit syncs the correct Python stdlib implementation from
upstream/main that includes:

- Python xml.etree.ElementTree for XML parsing
- urllib.request/urllib.error for HTTP with error handling
- try-except blocks for HTTP failures
- Validation that results were found
- ValueError handling for malformed versions
