New spelling of ObjectID type not working for DbObject types

**Describe the bug**
Our `DbObject` types are not updating to use the new syntax added in https://github.com/dotansimha/graphql-code-generator/pull/6831

```typescript
import { ObjectId } from 'mongodb';
export type CommunityDbObject = {
_id: ObjectID,
name: string,
access: string,
// ...
}
```

This causes type errors on build because `ObjectID` is not defined anywhere.

**To Reproduce**

Sandbox: https://codesandbox.io/s/affectionate-driscoll-0mjsq

(it stopped working when I tried to set it up so I can't see if it's actually working or not)

**Expected behavior**
The new `ObjectId` spelling of the type should be used in place of `ObjectID`.

**Environment:**

- OS: macOS 12.1 / `ubuntu-latest` from GitHub (happens everywhere)

**Additional context**

We are using a workaround where we stuff `import { ObjectID } from 'mongodb'` at the top of the file.
