fix : replace unsafe pickle.load with json in Word-Building data.py

[tmdeveloper007]

Summary of What Needs to be Done

Replace all pickle.load() and pickle.dump() calls in games/Word-Building/data.py with JSON-based serialization. pickle is unsafe because it can execute arbitrary Python code when deserializing untrusted data, which is a security risk if the words.bat data file is ever tampered with.

Changes that Need to be Made

• Replace import pickle with import json
• Replace pickle.load(file) with json.load(file)
• Replace pickle.dump(words, file) with json.dump(words, file, ensure_ascii=False)
• Rename words.bat to words.json to reflect the new format
• Update the WORDS_FILE path to use .json extension

Impact that it would Provide

• Eliminates arbitrary code execution risk from pickle deserialization
• Uses a standard, safe, cross-language serialization format
• Improves maintainability (JSON is human-readable for debugging)
