Can't use the template without targetting Android

The template suggests that you can use it for platforms other than Android. However when you remove the Android target you get this error:

```
Could not create task ':library:bundleAndroidMainClassesToCompileJar'.
Namespace not specified. Specify a namespace in the module's build file like so:
kotlin {
androidLibrary {
namespace = "com.example.namespace"
}
}
```

A KMP library should not mandatorily have to target Android.

Start by reproducing the failure after removing the Android target from the multiplatform library template, then inspect the module build configuration that produces the Android namespace error. Done means the template can be used without targeting Android and the build completes successfully.
