Remove the no-script flag in the LASTSAVE command

[enjoy-binbin]

Redis allow run it in the script:

127.0.0.1:6379> eval "return redis.call('lastsave')" 0
(integer) 1693277322

Look like a copy-paste bug.

another question, now run the no-script flag command will response this error:

127.0.0.1:6666> eval "return redis.call('lastsave')" 0
(error) ERR running script (call to f_d096f7c74e67ca72b33cecd3eb313f2d7732c9e6): This Redis command is not allowed from scripts

the error message mention This Redis command, maybe in the future we need to change this. since we may add some kvrocks-only commands?
