[dalito]

I also did a test install with poetry 2.1.1 (but without installing poetry-dynamic-versioning) and make setup ran without error till the end.

The template is not compatible with poetry 1.x, which does not understand the standard-conform pyproject.toml.

Side node: This step from the README

poetry self add "poetry-dynamic-versioning[plugin]"

is not required anymore.
