Additional remarks

• unsubscribe: If you don’t want to receive these PRs in the future, add skip: true to template-repos.yml using a PR or, if you never want to sync from the template again, delete your .cruft file.
• If there are merge conflicts, they either show up inline (>>>>>>>) or a .rej file will have been created for the respective files. You need to address these conflicts manually. Make sure to enable pre-commit.ci (see below) to detect such files.
• The scverse template works best when the pre-commit.ci, readthedocs and codecov services are enabled. Make sure to activate those apps if you haven't already.
