Add day-to-day work examples to the Meteor Admin Documentation

### Technical TODO

Currently the documentation only shows the Installation and API. It lacks examples/tutorials that users can work through to familiarize with the SDK.

Split it into these sections (as proposed by Lauri):

- [ ] **Development Cycle, including:**
- using Vue DevTools
- Finding Extension Points
- PositionId Discovery
- [ ] **Deployment**
- Bundling
- (Hosting?)
- [ ] **Running / Operating**
- Logging?
- [ ] **Updating / Maintenance**
- Handling Shopware upgrades and breaking changes
- Pushing a new version to the shops

Start by reviewing the existing Meteor Admin documentation for its Installation and API sections. Define the scope and structure for tutorials covering development, deployment, operation, and maintenance, then consider the work complete when each agreed day-to-day example is documented and usable by SDK users.
