Refactor to comply with template

[franklinlindemberg]

Changes in this PR:

• refactored python code since it was no longer working with the latest semantic-kernel library (and I didn't know which one was used by the time).
  • removed speech functions from semantic kernel (I dont think they belong there since they were called manually)
  • added query database as a semantic kernel plugin (now the chat will handle when it needs to fetch from the database automatically)
• refactored biceps module
  • remove unused codes
  • exported expected env variables
  • updated gpt name/version (the previous one was no longer available)
