Bug#1072183: fenics-dolfinx: FTBFS with nanobind 2.0

Hi Timo,
we are having issues making fenics-basix and fenics-dolfinx migrate to testing.
The issue is that the two downstream packages basix and dolfinx need to be
compiled with the same version of nanobind (so, 2.0+), but debci keeps picking
up pre-2.0 uploads when testing the other package.

Can you try adding the following Breaks to python3-nanobind
=========
Breaks: python3-basix (<< 0.8.0-3),
        python3-dolfinx (<< 1:0.8.0-8)
        python3-dolfinx-real (<< 1:0.8.0-8)
        python3-dolfinx-complex (<< 1:0.8.0-8)
=========

Looking at https://tracker.debian.org/pkg/nanobind it is very much possible that
only the Breaks on python3-dolfinx is required to allow migration, but the other
three still look meaningful to us.

Thanks,
Francesco
