text: Title:  Update supported Python versions to include 3.13, remove 3.8
  Body: ### Problem
  
  Per https://devguide.python.org/versions/, on 2024-10-07, Python 3.13 was officially released, and Python 3.8 is now end of life (EOL). The documentation mentions 3.8 but does not mention 3.12.
  
  ### Proposed Solution
  
  Test this extension with Python 3.13. Add support for 3.13 and remove 3.8 as a supported Python version.
