Remove dependency from metapackage issue template and create_package_template.py

We ask for package name and dependency in both the metapackage issue template and scripts/utils/create_package_template.py. Ask we rely on them being the same for automatic updates, to avoid bugs we should remove the duplication.

Start by comparing the metapackage issue template with scripts/utils/create_package_template.py, focusing on where package name and dependency are requested. Determine how automatic updates rely on those values being consistent. Done when the duplicate dependency request is removed and the remaining package-template workflow stays consistent.
