issue: 4633470 fix generate_docs.py +update README

Fix bug in generate_docs.py where non-dict properties caused processing
failures. Add proper type checking and error handling to prevent crashes
when encountering unexpected property types in the JSON schema.

Changes in generate_docs.py:
- Add type check to skip non-dict properties
- Wrap property processing in try-catch block
- Add error reporting with property path context

Regenerate README documentation with the fixed script:
- Document memory size suffix support (B, KB, MB, GB) for memory params
- Add missing threading behavior options (with_wakeup/no_wakeup)
- Simplify worker threads documentation for better clarity
- Fix inconsistent default value formatting

This ensures robust documentation generation and provides users with
complete information about memory size formatting and threading options.
