Fetching data from the Dog API

To implement shared networking, we will be using Ktor (https://kotlinlang.org/docs/mobile/use-ktor-for-networking.html) and kotlinx.serialization (https://github.com/Kotlin/kotlinx.serialization).

First, let's add the dependencies:

1. Add the following dependencies to the common source set:
   • io.ktor:ktor-client-core:$ktorVersion
   • io.ktor:ktor-client-json:$ktorVersion
   • io.ktor:ktor-client-logging:$ktorVersion
   • io.ktor:ktor-client-serialization:$ktorVersion
   • org.jetbrains.kotlinx:kotlinx-serialization-core:1.2.1
2. We also need to apply the kotlinx-serialization plugin, by adding kotlin("plugin.serialization") version kotlinVersion to the plugins block in the shared module's build.gradle.kts.
3. And we'll also need to add a dependency for the actual Ktor clients on the different platforms:
   • Add io.ktor:ktor-client-android:$ktorVersion to the Android source set.
   • Add io.ktor:ktor-client-ios:$ktorVersion to the iOS source set.
