[Bug] tctl does not allow signaling a workflow with more than one input

[antmendoza]

What are you really trying to do?

Send a signal to a workflow, one the signal method has more than one parameter.

According to the documentation https://docs.temporal.io/tctl-next/modifiers#--input
Pass input for the Workflow. Input must be in JSON format. For multiple JSON objects, pass each in a separate --input option.

When I try to signal a method with more than one parameter, the signal method only gets the last parameter (as the first parameter)

Tested with versions 1.17.2 and current

Describe the bug

Minimal Reproduction

Signal method:

@Override
    public void signalMethod2(String param1, String param2, String param3) {

      System.out.println("signalMethod2 param1 " + param1);
      System.out.println("signalMethod2 param2 " + param2);
      System.out.println("signalMethod2 param3 " + param3);
    }

Tctl command:

❯ tctl workflow signal --workflow_id 2b17fdca-3f5a-4906-8dde-c285f52be461 --name signalMethod2 --input \"hi\" --input \"hello\"  --input \"you\"

Console output:

signalMethod2 param1 you
signalMethod2 param2 null
signalMethod2 param3 null
