Nightly build for Python 3.10 does not yet contain set_output API

[mfeurer]

In order to try the new set_output API I installed the nightly build for Python 3.10, following these instructions.

However, sklearn.set_config does not yet have the argument transform_output, which can be verified by downloading the wheel and checking the file sklearn._config.py.

Since one of the builds is broken (cf. https://github.com/scikit-learn/scikit-learn/actions/runs/3278795901), we don't upload the nightly build.

It will be resolved once SciPy 1.9.3 is released which happen shortly: scipy/scipy#17239.

I just tested this again, and it looks like it made it into the nightly build!

Thanks @peterbolson for checking. I am closing this one then.
