fix: support Zabbix 6.0.5 by improving error matching

[slgray]

Closes #5135

📑 Description

Zabbix 6.0.5 returns error responses like:

{
  "jsonrpc": "2.0",
  "error": {
    "code": -32602,
    "message": "Invalid params.",
    "data": "Incorrect arguments passed to function."
  },
  "id": 1234
}

for the event.acknowledge method. These errors are not caught by the original logic that only checks for "Invalid parameter". This commit broadens the error matching to also handle "Incorrect arguments", ensuring the endpoint accessibility validation works correctly across Zabbix versions.
