Refresh LakeFS Python SDK API Reference Using MkDocs

[nopcoder]

The existing Sphinx-generated documentation for the LakeFS Python package (pydocs-lakefs.lakefs.io) is considered outdated in terms of user experience (UX). We aim to transition to MkDocs, which offers better UX for developers seeking detailed reference material.

Proposed Solution:

Migration out of current Python API references to use MkDocs. Reference the generated API reference documentation site from lakeFS Python documentation.
