refactor: update project structure and dependencies for Python 3.10+

[NiumXp]

• Added support for Python 3.11, 3.12, and 3.13.
  • Updated workflow tests accordingly.
  • Updated Python version classifiers in pyproject.toml.
  • Updated tox configuration to include the new Python versions for local testing.
• Increased the minimum required Python version to 3.10, as Python 3.8 is no longer receiving updates.
• Added a test step to ensure the package can be built successfully.
• Upgraded poetry to >=2 in both Dockerfile and poetry.lock.
• Removed unused files:
  • .github/PULL_REQUEST_TEMPLATE/bug_fix.md
  • deploy.sh
  • norminette/run_test.sh
• Removed setup.py and setup.cfg as the project now relies fully on poetry.
