Enhanced codegen config add maybeValue option

[lorenzofaresin]

Your use case

We need to use code generation with key?: T instead key: T | null because when we define gql query without some property we expect that the undefined property doesn't exists. That's different from exists with null value

The solution you'd like

edit generate.ts adding maybeValue: string with 'T | null' default on const codegenConfig {}
