Currently, we're using the maximum RDB version(12) when dumping the payload
which is not allowed in the old Redis versions(before Redis 7), so it
will throw the error:
```
127.0.0.1:6379> RESTORE a 0 "\x00\xc0{\x0c\x00\x83\x94g!\xfaP\xf9\xf0"
(error) ERR DUMP payload version or checksum are wrong
```
This PR changes the payload's RDB version to 6 for making it works with
the old Redis versions. And after applying this PR, it works well in
Redis 4/6:
```
127.0.0.1:6379> RESTORE a 0 "\x00\xc0{\x06\x00\xde\x0f;a\xf5/[*"
OK
127.0.0.1:6379> get a
"123"
127.0.0.1:6379> RESTORE a 0 "\x00\xc0{\x06\x00\xde\x0f;a\xf5/[*"
OK
127.0.0.1:6379> get a
"123"
```
