feat: enhance postmanTranslation for multiline untranslated pm commands

[sanish-bruno]

Description

Currently untranslated pm commands, only the first line gets commented out, making the script break,
with this implementation, it should ideally comment out the entire block related to it. added tests check this condition

const inputScript = `
      pm.sendRequest({
        url: "https://jsonplaceholder.typicode.com/posts/1",
        method: "GET",
        header: {
            "Content-Type": "application/json"
        }
      }, function (err, res) {
          if (err) {
              console.log("Request Error:", err);
          } else {
              console.log("Dynamic Request Status:", res.code);
              pm.environment.set("response_data", res.json());
          }
      });
    `;

  const expectedOutput = `
//       pm.sendRequest({
//         url: "https://jsonplaceholder.typicode.com/posts/1",
//         method: "GET",
//         header: {
//             "Content-Type": "application/json"
//         }
//       }, function (err, res) {
//           if (err) {
//               console.log("Request Error:", err);
//           } else {
//               console.log("Dynamic Request Status:", res.code);
//               bru.setEnvVar("response_data", res.json());
//           }
//       });
    `;
