Missing exit codes on "fetch" scripts

[dev-davva]

Description

The scripts utilising fetch are currently swallowing exceptions (deploy.js, deploy-prod.js, create-addon.js, etc..)

When calling the script from a terminal, it will always report back as successful, even if it has failed.
This causes problems with CI/CD pipelines, that rely on exit codes to present results and handle control flow.

Expected behaviour

try {
  const response = await fetch(url, {
...
  });

  handleResponse({ response, operation: 'Upload' });
} catch (err) {
  console.log(`${chalk.red('Upload failed, status code:')} ${err}`);
  // exit with error code here, or maybe re-throw exception to handle it further up the call chain?
}

Current behaviour

try {
  const response = await fetch(url, {
...
  });

  handleResponse({ response, operation: 'Upload' });
} catch (err) {
  console.log(`${chalk.red('Upload failed, status code:')} ${err}`);
  // exception is being swallowed here
}
