doc(ai): sync hugegraph-python-client with main

[bitflicker64]

Syncs the HugeGraph Python client quick start (en and cn) with apache/hugegraph-ai@main at version 1.7.0. Every change below traces to a file on main.

Note on the PyPI package name

hugegraph-python on PyPI is the Apache-published distribution (latest 1.5.0, author Apache HugeGraph Contributors <dev@hugegraph.apache.org>). hugegraph-python-client on PyPI is an unrelated empty 0.1.1 placeholder with no author, license or project URLs. The repo declares the distribution as hugegraph-python-client 1.7.0, but nothing has shipped under that name. The install command is therefore left as hugegraph-python and the naming and version gap is documented on the page, rather than "fixed" into a command that does not work.

Page	Wrong	Changed to	Source
en + cn	uv sync from the repo root installs the client	uv sync --extra python-client; the client is a workspace member reached only through that extra	pyproject.toml:40,93-97, .github/workflows/hugegraph-python-client.yml:52
en + cn	Requirements said only "An accessible HugeGraph Server"	HugeGraph Server 1.5.0 or later; the client raises RuntimeError on older servers and points at client v1.3.x	hugegraph-python-client/src/pyhugegraph/utils/huge_config.py:66-71

Upstream defects found while reading the code

Not fixed here, they belong in apache/hugegraph-ai. hugegraph-python-client/README.md is stale in ways the doc pages no longer are:

• README.md:48 calls PyHugeClient("127.0.0.1", "8080", user=..., pwd=..., graph=..., graphspace=...), which raises TypeError against the current signature, since graph is the second positional parameter (src/pyhugegraph/client.py:50-59).
• README.md:124-160 uses addVertex('person').property(...).create(), updateVertex(...), deleteVertex(...) and deleteEdge(...), none of which exist on GraphManager (src/pyhugegraph/api/graph.py).

Correction for a page this PR does not own

content/en/docs/quickstart/client/hugegraph-client.md:11 and its cn counterpart link the Python client to the GitHub source tree, https://github.com/apache/hugegraph-ai/tree/main/hugegraph-python-client, while the sibling Go client link is an internal doc link. It should point at /docs/quickstart/client/hugegraph-client-python instead, now that this page is the fuller reference. Left for the owner of that page.
