NextDrupalBase cannot be used in enableDraftMode()

[JohnAlbin]

Package containing the bug

next-drupal (NPM package)

Describe the bug

In the /draft entry point, the enableDraftMode() function accepts a NextDrupal object as its second parameter:

async function enableDraftMode(
  request: NextRequest,
  drupal: NextDrupal
): Promise<Response | never> {

enableDraftMode() then uses that drupal object's validateDraftUrl() method.

That validateDraftUrl() is actually a method of the NextDrupalBase class, so theoretically a developer should be able to pass a NextDrupalBase object to enableDraftMode() and it should work. But the type definition of NextDrupal prevents that; a TypeScript error is thrown during a TS build.

Expected behavior

A developer should be able to pass a NextDrupalBase object to enableDraftMode() and the TypeScript compilation should not fail and, when the code is run, draft mode should be enabled.
