Current Behavior

npm pack with a specific commit of a git dependency fails as follows:

$ npm pack vercel/ms#1304f150b38027e0818cc122106b5c7322d68d0c                                   
npm ERR! GitFetcher requires an Arborist constructor to pack a tarball

npm ERR! A complete log of this run can be found in: /home/acmiel/.npm/_logs/2023-08-21T08_27_53_861Z-debug-0.log

Expected Behavior

Expected npm pack to succeed (like it does in version <= 9.6.4).

Note that it still works for things that are not commit hashes:

$ npm pack vercel/ms#3.0.0-canary.1
...
ms-3.0.0-canary.1.tgz

Steps To Reproduce

1. With npm version 9.6.5 or higher
2. Run npm pack vercel/ms#1304f150b38027e0818cc122106b5c7322d68d0c or any other git dependency + commit hash
3. And get npm ERR! GitFetcher requires an Arborist constructor to pack a tarball
