proposal: test against `lightgbm` nightly packages?

Description

As of https://github.com/lightgbm-org/LightGBM/issues/7227, LightGBM now publishes nightly Python packages.

To test against the latest development version of lightgbm, you can install them like this:

pip install \
    --no-deps \
    --index-url https://pypi.anaconda.org/lightgbm-packages/simple \
    'lightgbm>=4.6.0a0'

We're publishing an sdist and wheels for all of the same platforms that are published to pypi.org (https://pypi.org/project/lightgbm/#files).

Benefits of this change

I hope you'll consider testing against the nightlies here, so we can mutually fix compatibility issues before releases go out.

We (LightGBM) have been doing that with scikit-learn nightlies for a few years now and have found it very useful.

If you do take this up, please report any issues you find at https://github.com/lightgbm-org/LightGBM/issues.

Thanks very much for your time and consideration.
