Change destination key's key-spec flag from RW to OW for SINTERSTORE command (#12917)

In #10122, we set the destination key's flag of SINTERSTORE to `RW`, 
however, this command doesn't actually read or modify the destination
key, just overwrites it.
Therefore, we change it to `OW` similarly to all other *STORE commands.
