fix(View): Handle ICacheEntry returned by FileInfo->getData()

[provokateurin]

server/lib/private/Files/FileInfo.php

Line 21 in 7005bd2

private array|ICacheEntry $data;

can be an array or ICacheEntry, so we need to handle it and turn it into an array. Otherwise

server/lib/private/Files/View.php

Line 1679 in 7005bd2

return $cache->put($internalPath, $data);

fails, because it expects an array.
