The script buildscripts/idl/checkout_idl_files_from_past_releases.py checks out IDL files from a sparse git checkout.
The git show operations it executes on individual files may need to fetch the object from the remote origin. This requires network connectivity and can fail in cases of connectivity issues.

A retry mechanism should be added to the git show command, so that when it fails, it can be retried a few times before ultimately failing.
