[BUG] Document upload validation schema issues with vercel blob

[kprocks86]

when setting up the full project in local and when i went to upload the pdf document i get Errors in API POST /api/teams/{teamId}/documents

Document upload validation failed for teamId: xxx.

Errors: [
     {
       "code": "custom",
       "message": "File path must be either a Notion URL or an file storage path",
       "path": ["url"]
     },
     {
       "code": "custom", 
       "message": "Storage type does not match the URL/path format, or missing storage type for non-Notion files",
       "path": ["storageType"]
     }
   ]

this below is the request body that is matching against documentUploadSchema

  const testReqBody = {
     name: 'Test Document.pdf',
     url: 'https://example123.public.blob.vercel-storage.com/test-doc.pdf',
     storageType: 'VERCEL_BLOB',
     numPages: 5,
     type: 'pdf',
     contentType: 'application/pdf',
     createLink: false,
     fileSize: 102400
   };

I am testing this in my local development environment
I found out that VERCEL_BLOB_HOST env variable is not present in .env.example env is not uptodate
This issue might come only to the people who are setting up the local system first time.
