Enable uv/pdm install from Git

[mafr]

The package version is managed in Cargo.toml, not in pyproject.toml. While "pip install" from Git works fine, it doesn't work from uv or pdm. Installation stops with a parse error:

pyproject.toml is using the [project] table, but the required project.version field is neither set nor present in the project.dynamic list

Marking version as dynamic seems to be the official solution.

Thanks for this!
