Add lower restrictions on dolfinx and ufl version

[janmirco]

Colleagues of mine and I started using your project to tackle problems in nonlinear solid mechanics. Firstly, thank you for your work! Without your project, I did not see any way of using FEniCSx for my research. This stems from the approach we use for our material models.

I had issues installing the latest version of dolfinx-external-operator. I am using FEniCSx 0.9 with conda. Lowering the restrictions on the version of dolfinx and ufl, solved this issue for me.

My fenics setup:

dolfinx-external-operator 0.10.0.dev0              pypi_0    pypi
fenics-basix              0.9.0           py313h867a91d_2    conda-forge
fenics-basix-nanobind-abi 0.2.1.13             h6c05e69_2    conda-forge
fenics-dolfinx            0.9.0         py313h041dec1_108    conda-forge
fenics-ffcx               0.9.0              pyh2e48890_0    conda-forge
fenics-libbasix           0.9.0                h7cb7ce6_2    conda-forge
fenics-libdolfinx         0.9.0              hb85e8c2_108    conda-forge
fenics-ufcx               0.9.0                hb7f7608_0    conda-forge
fenics-ufl                2024.2.0           pyhd8ed1ab_1    conda-forge

Dear @janmirco

It seems that you installed FEniCSx v0.9 and the development version of dolfinx-external-operator. The development version is typically compiled against dolfinx:nightly, so it may not be compatible with the latest release of dolfinx. To install the release v0.9.0 of dolfinx-external-operator you need just this

pip install git+https://github.com/a-latyshev/dolfinx-external-operator.git@v0.9.0

@jhale, What do you think of lowering the version requirement to let conda users run the latest release?
