Bug#1111280: transition: pandas 2.2 -> 2.3

[Rebecca N. Palmer]

dask, xarray, etc have now passed their autopkgtests.

Since this looked like a problem-free transition, I ran the build test 
only for packages that didn't have a (non-superficial) autopkgtest.  It 
found two issues:

- pandas.__version__ includes the +dfsg suffix.  Such versions are 
allowed by the Python packaging spec ( 
https://packaging.python.org/en/latest/specifications/version-specifiers/#local-version-identifiers 
), but mlpack's build considers them invalid.

This was probably triggered by starting to use pyproject / mesonpy, but 
it's unclear how general a problem it is.  Of the other mesonpy 
packages, matplotlib also has it in meson's "Project version" (I haven't 
checked the final package) but numpy and scikit-misc don't.

- tqdm's tests fail on warnings, and trigger one of the new warnings.
