Copy project.dependencies to conda runtime dependencies

[peterfpeterson]

It appears that project.dependencies and tool.pixi.package.run-dependencies can disagree and pixi doesn't care. This copies the project dependencies down to the packaging stage.

To test:

pixi run build-conda and scroll back to the listing of runtime dependencies.

It is not sufficient to pip install the software since the conda package is what is broken.
