Fix wordsteam.py: Python 3 compatibility and polyglot HTTP 403 errors

Summary

This PR addresses two critical issues preventing Chapter 3's wordsteam.py script from running:

1. Python 2 to 3 syntax incompatibility: Updated all print statements to use Python 3 parentheses syntax
2. Polyglot library HTTP 403 errors: The polyglot library fails when attempting to download morpheme models from deprecated servers

Three solutions provided:

• Fixed original script (3_1_wordsteam.py): Python 3 compatible, but polyglot may still fail
• Polyglot patcher (polyglot_downloader_patch.py): Adds User-Agent headers to help bypass server restrictions (may not fully resolve the issue)
• NLTK-only alternative (3_1_wordsteam_nltk_only.py): Recommended - Works reliably without polyglot dependencies, demonstrates Porter, Lancaster, and Snowball stemmers

Review & Testing Checklist for Human

• Verify Python 3 syntax changes in 3_1_wordsteam.py are complete (all print statements updated correctly)
• Test the NLTK-only script (3_1_wordsteam_nltk_only.py) - This is the recommended solution and should work out of the box with just pip install nltk
• Review documentation clarity in FIXES_README.md - Is it clear which solution users should choose? Does it adequately explain the polyglot issues?
• Verify the patch script (polyglot_downloader_patch.py) - It modifies an external library file. Consider whether this approach is appropriate or if we should just recommend the NLTK alternative
• Decide on polyglot support: Given that polyglot is deprecated (last updated 2016) and its servers are unreliable, should we even try to maintain support or just recommend the NLTK alternative?

Test Plan

# Test NLTK-only solution (should work reliably)
pip install nltk
python3 ch3/3_1_wordsteam_nltk_only.py

# Optional: Try the patched polyglot approach
# Note: May still fail due to server issues
sudo apt-get install libicu-dev pkg-config
pip install polyglot PyICU pycld2 morfessor numpy six
python3 ch3/polyglot_downloader_patch.py
python3 ch3/3_1_wordsteam.py

Notes

Known limitations:

• Even with the patch, polyglot morpheme functionality may still fail because the project's infrastructure is deprecated and unreliable
• The patch script modifies the installed polyglot library files - users will lose the patch if they reinstall polyglot
• The polyglot library hasn't been updated since 2016 and has various Python 3 compatibility issues

Why the NLTK-only solution is recommended:

• No external server dependencies
• Well-maintained library
• Demonstrates multiple stemming algorithms (Porter, Lancaster, Snowball)
• Actually provides more educational value than the original
