The keyDB instance is called redis in lua

[merlinthemagic]

Hi,

Likely not an oversight, since there are several issues regarding lua scripts that happily refer to the KeyDB instance as redis.
But the documentation says otherwise, so i thought i would note it.

version: keydb-6.3.2-1.el7.x86_64
OS: CentOS7

Docs: https://docs.keydb.dev/docs/distlock/#correct-implementation-with-a-single-instance

From article:

if KeyDB.call("get",KEYS[1]) == ARGV[1] then
return KeyDB.call("del",KEYS[1])
else
return 0
end

Result is the server floating the following error:

@enable_strict_lua:15: user_script:1: Script attempted to access nonexistent global variable 'KeyDB'

Change the referance from KeyDB to redis and the script executes as expected.
