fix(light-model-client): expose modelql-untyped as a dependency

Converts the implementation dependency of light-model-client on
modelql-untyped into an api dependency as the base class of a
LightModelClient instance is part of that package. Otherwise, downstream
projects might fail to build due to being unable to resolve the base
class.

Fixes: MODELIX-496
