text: Title: [Storage] Bump GCSFuse to 2.4.0+
  Body: [GCSFuse 2.4.0](https://github.com/GoogleCloudPlatform/gcsfuse/releases/tag/v2.4.0) introduces parallel downloads which helps with loading large files (e.g., model checkpoints).
  
  We should bump GCSFuse version + investigate the tradeoffs of enabling parallel downloads (by setting `file-cache:enable-parallel-downloads:true` in the gcsfuse config file).
