GraphQL related build failures after migrating @nestjs/graphql package to v8

Regression

Checked migration docs v7 to v8 and GraphQL related module or type errors are not mentioned.

Describe the regression

I tried upgrading @nestjs/graphql to v8 and failed. I used the following code to reproduce the issue. Rolling back to @nestjs/graphql@7 solved my issues.

Input Code

Reproduction:

npm i -g @nestjs/cli@8
nest new project-name -> choose `npm`
cd project-name
npm run build

No failures so far. Now I followed the GraphQL Quickstart Tutorial

npm i @nestjs/graphql graphql-tools graphql apollo-server-express
nest g res example -> choose `GraphQL (code first)`
npm run build

I'm receiving the following errors:

Expected behavior/code

I was not expecting module or type declaration errors when migrating from @nestjs/graphql@7 to @nestjs/graphql@8. Neither migration docs nor Nest GraphQL docs mention potential issues or give instructions.

Nevertheless, rolling back @nestjs/graphql@7 resolves all build errors. So the upgrade of apollo-server-express package from 2.25.2 to 3.0.0 seems not to be the problem.
