Replace non-existent python:3.14.1 base image tag

The Dockerfile now uses FROM python:3.14.1, but the official Python images have not shipped a 3.14 series yet (current tags stop at 3.12/3.13), so any Docker build for the GitHub Action will fail immediately when it cannot pull the base image. Please keep the base image on an available tag (e.g., a released Python version) to avoid breaking the action build.

Bug: Invalid Python version upgrade breaks Docker build

The upgrade from python:3.9 to python:3.14.1 references a Python version that doesn't exist - Python 3.14 has not been released. Additionally, the project's setup.py classifiers and CI workflow only declare support for Python 3.6-3.9, and many dependencies have upper version bounds (like invoke>=1.4.1,<2, pytest>=5,<6, twine>=3,<4) that may be incompatible with newer Python versions. This Docker image will fail to build because the python:3.14.1 base image doesn't exist on Docker Hub.
