icav2 projectdata s3-sync-* help page is ambiguous

```
    icav2 projectdata s3-sync-upload <upload_path> <data>
                                     [-w<file_path> | --write-script-path=<file_path>]
                                     [--s3-sync-arg=<s3_sync_arg>]...

```

`<upload_path>` should be `<src_path>`
