encrypted should probably not get set or at least not to the version?

When I tested it, just setting encryptedVersion "corrupts" the version but also setting encrypted fixes the issue.

I guess we already do some of this below too, but I feel like we should be letting the Encryption storage wrapper deal with these matters -- e.g.

server/lib/private/Files/Storage/Wrapper/Encryption.php

Lines 644 to 654 in 2da90a9

private function copyBetweenStorage(
Storage\IStorage $sourceStorage,
string $sourceInternalPath,
string $targetInternalPath,
bool $preserveMtime,
bool $isRename,
): bool {
// for versions we have nothing to do, because versions should always use the
// key from the original file. Just create a 1:1 copy and done
if ($this->isVersion($targetInternalPath)
|| $this->isVersion($sourceInternalPath)) {

]
);

$versionCreated = true;
}
