Docs use dynamic python version from pypi

[cpaniaguam]

This pull request updates the documentation and project metadata to more accurately reflect supported Python versions.

Documentation update:

• Updated the Python version badge in README.md to dynamically show all supported versions via PyPI, instead of listing specific versions.

Project metadata:

• Added explicit Python version classifiers (3, 3.11, 3.12, 3.13) to pyproject.toml for clearer compatibility information.

Pull request overview

This PR modernizes the Python version documentation by replacing a static badge with a dynamic PyPI-sourced badge and adding explicit version classifiers to project metadata.

• Updated README.md to use a dynamic shields.io badge that automatically reflects supported Python versions from PyPI
• Added Python version classifiers (3, 3.11, 3.12, 3.13) to pyproject.toml, consistent with the existing requires-python = ">3.10, <3.14" constraint

I've completed my review of this pull request. The changes are well-implemented and consistent:

1. README.md: The new badge URL https://img.shields.io/pypi/pyversions/lanfactory is the correct format for shields.io to dynamically display Python versions from PyPI metadata.

2. pyproject.toml: The added classifiers (Python 3, 3.11, 3.12, 3.13) correctly match the existing requires-python = ">3.10, <3.14" constraint, which supports Python 3.11, 3.12, and 3.13.

The changes align perfectly with the PR description and achieve the stated goal of making the Python version documentation more maintainable by sourcing it from PyPI rather than requiring manual updates.

Thanks @cpaniaguam this is great. Failed on that before.
Could we apply the same solution across all three packages?
