[Documentation]: Differences between some dependency graph images and actual dependencies

### What's the documentation problem or suggestion?

The dependency graph images have been very helpful in understanding the module dependencies.
However, there are differences between the images and the actual implementation.

For instance, the `core:data` module depends on the `core:database` module, but this is not reflected in the diagram.

https://github.com/android/nowinandroid/blob/main/core/data/build.gradle.kts

There are also some other modules where the diagram is not accurate.

### Code of Conduct

Start by comparing docs/images/graphs/dep_graph_core_data.png with core/data/build.gradle.kts, then inspect the other dependency graph images and corresponding module build files for mismatches. Done means every affected graph accurately reflects the actual module dependencies, including core:data depending on core:database.
