Params with the Args decorator are not decorated in resolvers after inheritance

Is there an existing issue for this?

Current behavior

When I create a new resolver by extending an existing resolver, fields that had Args decorators do not have the corresponding graphql params. For example, given:

import { Args, Int, Query, ResolveField, Resolver } from '@nestjs/graphql';
import { Author } from './models/author.model';

@Resolver((of) => Author)
export class AuthorsResolver {
  constructor() {}

  @Query((returns) => Author)
  async author(@Args('id', { type: () => Int }) id: number) {
    return { id };
  }

  @ResolveField()
  async posts(@Args('language') language: string) {
    return [{ id: 1 }];
  }
}

When I extend the resover like this,

import { Args, Int, Query, Resolver } from '@nestjs/graphql';
import { AuthorsResolver } from 'src/authors/authors.resolver';
import { Blog } from './models/blog.model';

@Resolver((of) => Blog)
export class BlogsResolver extends AuthorsResolver {
  constructor() {
    super();
  }

  @Query((returns) => Blog)
  async blog(@Args('id', { type: () => Int }) id: number) {
    return { id };
  }
}

Then I expect to be able to query posts like this

  blog(id:$id) {
    posts(language:"en") {
      id
    }
  }

Currently this is an error:

        "message": "Unknown argument \"language\" on field \"Blog.posts\".",

Minimum reproduction code

https://github.com/andre-byrne/args-not-inherited-example/tree/main

Steps to reproduce

npm i
npm run start
in the playground try this:

query ($id: Int!) {
  author(id:$id) {

    posts(language:"en") {
      id
    }
  }

  blog(id:$id) {
    posts(language:"en") {
      id
    }
  }
}

You will see that the blog field does not permit the language argument.

Expected behavior

When I create a new resolver by extending an existing resolver, I expect all the fields from the parent class to be present in my new resolver just as they were in the parent. If the parent has a posts field with a language argument, then the child should have a posts field with a language argument.
