Temporary removal of OneNote file size check (#4437)

Temporarily remove the large file size check that controls skipping a OneNote file download that failed with a
503 error.

We've observed this error condition to be persistent even with smaller OneNote files.

This allows us to unblock backup for these resources while we investigate the issue.
