Manifest generation for projects only using Python in pre-rendering should include Python

I have a project in which I only use a Python script in pre-rendering, but not in any .qmd files. Generating a manifest through:

rsconnect write-manifest quarto . --overwrite

causes the "python" section to not appear, which prevents the requirements.txt from being included, and it seems no Python environment is set up when deploying. The pre-render scripts then fail because they can't import my dependencies.

As a workaround I just added an empty Python cell to one of my .qmd files.

It would be nice if the manifest would also include Python things when there are Python scripts used in pre-rendering.

Empieza reproduciendo rsconnect write-manifest quarto . --overwrite con un proyecto que use Python únicamente en un script de pre-renderizado y, después, inspecciona la ruta de generación del manifiesto de Quarto. Compara el resultado con un proyecto que contenga una celda de Python; la tarea estará terminada cuando el manifiesto incluya la sección de Python y requirements.txt, de modo que el despliegue configure el entorno para el script de pre-renderizado.
