Is your feature request related to a problem? Please describe it

Currently the only way to enable sortSchema: true is via the GraphQLModule's GqlModuleOption but the sortSchema option isn't available in its GenerateOptions type.

When using a schema first approach, this means the only way to generate a sorted schema is to run the NestJS app that instantiates the GraphQLModule. This is a bummer because the example script shown in the schema first documentation only uses the GraphQLDefinitionsFactory.

Describe the solution you'd like

GraphQLDefinitionsFactory should allow the same sortSchema option in its GenerateOptions.

What is the motivation / use case for changing the behavior?

It should be possible to generate the same GraphQL schema via GraphQLModule and GraphQLDefinitionsFactory.
