feat!: require Shopware 6.7, release as 0.1.0

- shopware/core ~6.7.0; 6.6 stays on the 0.0.x line
- drop the sw-settings navigation entry; the settingsItem card in
  Settings > System is the only entry, like core settings modules
- dev container on dockware/shopware:6.7.14.2

BREAKING CHANGE: Shopware 6.6 is no longer supported.
