Original GitHub issue: https://github.com/atulmy/gql-query-builder/issues/89

In index.ts, the type for a query adapter is any, while for the mutation or subscription adapters, they are limited to IMutationAdapter or ISubscriptionAdapter

function queryOperation(
  options: IQueryBuilderOptions | IQueryBuilderOptions[],
  adapter?: any,
  config?: any
)
...
function mutationOperation(
  options: IQueryBuilderOptions | IQueryBuilderOptions[],
  adapter?: IMutationAdapter,
  config?: any
) 
...
function subscriptionOperation(
  options: IQueryBuilderOptions | IQueryBuilderOptions[],
  adapter?: ISubscriptionAdapter
)

If I try to create my custom adapters, I will be able to create a Query Adapter without issues, but for a Mutation Adapter like this:

    const query = buildMutation({
        ...myOptions
    }, MyMutationAdapter);

I will get a compilation error like this: Type 'typeof MyMutationAdapter' is missing the following properties from type 'IMutationAdapter': mutationBuilder, mutationsBuilder , even though MyMutationAdapter implements both methods
