fix(formatFileSize): Fix default value for binaryPrefixes

The default was previously on Nextcloud core set to true, so bytes were formatted using base 2.
(But the wrong unit was used, e.g. 1024 byte were formatted as 1 KB).
This reverts the default to format sizes using the binary format (1024 = 1 KiB).
