Support for returning void from GraphQL Mutation

[zbhavyai]

By default GraphQL does not support returning nothing. It would be nice to have return void or Uni<Void> from a GraphQL mutation in the smallrye's implementation. Right now, if a mutation returns void, an exception is thrown graphql.AssertException: type Void not found in schema. I am using smallrye-graphql extension in Quarkus.

Thank you.
