template-init workflow does not replace placeholder description

[marksverdhei]

Problem

pyproject.toml contains the placeholder description "Add your description here". The template-init.yml workflow replaces python-template and python_template occurrences but does not update or remove this placeholder description.

Suggested fix

Either replace the description with the repo's GitHub description (available via ${{ github.event.repository.description }}), or remove the placeholder so the user is prompted to fill it in.
