Enable ruff built in linter rules

[TimPansino]

Overview

• Enable ruff's built in linter rules.
  • Remove unicode characters in sample AI responses.
  • Disable 1 instance of a dangling asyncio task rule violation as intentional.
  • Fix all other violations.
• Permanently disable flake8-self linter rules in ruff.
  • Only rule is private member access, which is done intentionally and would therefore be disabled. Disable entire linter instead.
• Remove GitHub status reporter for Megalinter and just use comment reporter.
  • Status reporter seems to frequently fail to update and is deprecated.
