[FLINK-39031][python] Build pyflink wheels for Python 3.13

[florianvazelle]

What is the purpose of the change

This pull request adds Python 3.13 to the pyflink wheel build matrix.

It depends on two other PRs and should be merged after them:

• drop EOL manylinux2014 (cibuildwheel 2.16.5 has no cp313 identifiers, and Pillow no longer ships manylinux2014 wheels) [FLINK-40464][python] Build pyflink wheels on manylinux_2_28 #29016
• bump pemja to 0.6.1 (0.5.7 has no cp313 wheel) [FLINK-39997] Upgrade pemja to 0.6.1 #28550

Python 3.14 is left out: pemja still has no cp314 wheel.

Brief change log

• Add cp313-* to [tool.cibuildwheel] build in flink-python/pyproject.toml
• Include 3.13 in the local wheel / lint Python env lists
• Advertise Programming Language :: Python :: 3.13 in setup.py

Verifying this change

This change is a packaging / classifier update without unit-test coverage.

• After the two blocking PRs land, nightly build_python_wheels and Azure build-wheels.sh should produce cp313 wheels
• python_requires / classifiers should list 3.13
• Existing 3.9-3.12 wheel builds should be unchanged

Does this pull request potentially affect one of the following parts:

• Dependencies (does it add or upgrade a dependency): no (pemja bump is a separate PR)
• The public API, i.e., is any changed class annotated with @Public(Evolving): no
• The serializers: no
• The runtime per-record code paths (performance sensitive): no
• Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn, ZooKeeper: no
• The S3 file system connector: no

Documentation

• Does this pull request introduce a new feature? no
• If yes, how is the feature documented? not applicable
