Description

1. bulkWrite will show a typescript error if passed a variable of type AnyBulkWriteOperation<ISchema>[]

Steps to Reproduce

function modelBulkTest() {
  interface ISchema {
    _id: string;
    num: number;
  }

  const schema = new Schema({
    _id: { type: String },
    num: Number
  });

  const M = model<ISchema>('Test', schema);

  const ops: AnyBulkWriteOperation<ISchema>[] = [
    {
      updateOne: {
        filter: { _id: 'test' },
        update: {
          $inc: { num: 1 }
        },
        upsert: true
      }
    }
  ];
  M.bulkWrite(ops);
}

const ops: AnyBulkWriteOperation<ISchema>[]
Argument of type 'AnyBulkWriteOperation<ISchema>[]' is not assignable to parameter of type 'AnyBulkWriteOperation<Document>[]'.
  Type 'AnyBulkWriteOperation<ISchema>' is not assignable to type 'AnyBulkWriteOperation<Document>'.
    Type '{ insertOne: InsertOneModel<ISchema>; }' is not assignable to type 'AnyBulkWriteOperation<Document>'.
      Type '{ insertOne: InsertOneModel<ISchema>; }' is not assignable to type '{ insertOne: InsertOneModel<Document>; }'.
        The types of 'insertOne.document' are incompatible between these types.
          Type 'OptionalId<ISchema>' is not assignable to type 'OptionalId<Document>'.
            Type 'OptionalId<ISchema>' is not assignable to type '{ _id?: ObjectId | undefined; }'.
              Types of property '_id' are incompatible.
                Type 'string | undefined' is not assignable to type 'ObjectId | undefined'.
                  Type 'string' is not assignable to type 'ObjectId'.

Expected Behavior

The test should pass.

@vkarpov15 The issue is that AnyBulkWriteOperation treated AnyBulkWriteOperation<Document> for each and every model and unable to accept anything, except for AnyBulkWriteOperation<Document> or any, while it should be able to accept AnyBulkWriteOperation<TSchema> by default.

Should be fixed by #12167
