Implement input function for Bruno GUI

[jthln]

I have checked the following:

Describe the feature you want to add

It would be helpful, if we could ask for user input in pre-request/post-response sections of the Bruno GUI somehow.

I tried some approaches, but to no avail so far (not a frontend developer, please bear with me):

• Javascript prompt does not work (prompt is not defined)
• Installing and using npm prompt-sync does not work (ENXIO: no such device or address, open '/dev/tty')

script:pre-request {
  const prompt = require('prompt-sync')();
  const answer = prompt('Please enter firstname:');
  console.log(`You entered: ${answer}`);
}

• Installing and using npm readline does not work (Operation not allowed on contextified object.)

script:pre-request {
  const readline = require('readline');
  const rli = readline.createInterface({
    input: process.stdin,
    output: process.stdout
  });
  rli.question('Please enter firstname: ', (answer) => {
    console.log(`You entered: ${answer}`);
    rli.close();
  });
}
