Add missing modules to runtime (#219)

Updates the runtime plugin config to include the same modules the
smithy-cli does:
https://github.com/smithy-lang/smithy/blob/fb9ef6dafe89742eefb87f0072b4c7762afd70d9/smithy-cli/build.gradle.kts#L99.
Otherwise, we get some class defs not found when resolving dependencies.
I don't have a good idea for how to avoid the duplication between the
repos.
