Unresolved reference: Repository

Nobody has claimed this yet.

### Expected Behavior

I'm trying to add micronaut-data to an existing project. The docs say to add the following to gradle, which doesn't work:
```kotlin
annotationProcessor("io.micronaut.data:micronaut-data-processor")
```

I'm getting the error `Unresolved reference: Repository` when I try to add the `@Repository` annotation to an interface. The docs mention a runtime dependency, but they don't tell what it is. This is basic stuff guys, I shouldn't have to do an hour of research to figure out all of the required packages, this needs to be in the docs. The docs seem to assume that you're going to regenerate a new micronaut starter project every time, which isn't convenient at all.

After further research, it looks like there are a variety of possible dependencies scattered throughout the docs. These should all be moved to up at the top under the `Build Configuration` heading, and it should be clearly stated that you have to install one of them. As a user, I should be able to install micronaut-data and start using it quickly, without having to read and understand the entire documentation. There needs to be a "getting started" section that clearly states what you need to do to install it and get started, just like most other libraries.

### Actual Behaviour

The docs should correctly state how to install micronaut-data.

### Version

Locate the micronaut-data documentation's Build Configuration content and the dependency examples scattered through the docs. First compare the documented annotationProcessor setup with the runtime dependencies needed for the @Repository example. Done means a newcomer can find a getting-started section, identify the required dependency options, and install micronaut-data without reading the full documentation.
