Hi!

I noticed that since a couple days ago, our CI's daily run at https://github.com/widgetti/solara is failing due to a build error for this package (see, for instance, this run). The error is:

  💥 maturin failed
    Caused by: `project.version` field is required in pyproject.toml unless it is present in the `project.dynamic` list

Looks like since the last release of maturin, setting project.version either statically or dynamically in pyproject.toml is required, as per PyO3/maturin#2391.

Could this be added to the project?
