fix!: update ora stream output

[Yoon-Hae-Min]

What is Different

test code

const { spawn } = require("child_process");

const run = () => {
  const command = "yarn";
  const args = ["gen:example"];

  const childProcess = spawn(command, args);

  childProcess.stdout.on("data", (data) => {
    console.log(`stdout: ${data}`);
  });

  childProcess.stderr.on("data", (data) => {
    console.error(`stderr: ${data}`);
  });

  childProcess.on("close", (code) => {
    if (code !== 0) {
      console.error(`Command finished with code ${code}`);
    } else {
      console.log("Command finished successfully");
    }
  });

  childProcess.on("error", (error) => {
    console.error(`Execution error: ${error}`);
  });
};

run();

Before

After

Why

In the previous execution method, the yarn gen:example command mistakenly routed validation messages to the standard error stream (stderr). Despite these messages being part of normal feedback rather than errors, this misrouting could confuse users. In this update, such messages are correctly routed to the standard output stream (stdout), ensuring that general process information is accurately conveyed to the user.

Hey @Yoon-Hae-Min,

Thanks for your PR, non-error shoud indeed go to stdout.

I believe this would be a breaking change in ts-to-zod I/O as some people might rely on checking stderr in their pipeline, and we would need to release this into a new major.
As other breaking changes are needed ( breaking This issue introduces a breaking change that would go into a new Major version ), maybe now would be the time to implement and create a new major.

WDYT @fabien0102 & @schiller-manuel ?
