Using src:true isn't work in new Node versions.

const log = bunyan.createLogger({
  name: "test",
  src: true,
});

Fixes: #714

As of Node 20.1.0 if you don't call new Error() the method prepareStackTrace isn't called.

Nodejs issue: nodejs/node#49681

Before the correction, using a Node version starting from 20.1.0, log.info returns an empty src.

//index.js
const bunyan = require("bunyan");
const log = bunyan.createLogger({name: "test", src: true});
log.info("test");

$ nvm use 18
$ node index.js

$ nvm use 20.5.0
$ node index.js

TESTS

There is a test for src named: src.test.js and using node version 20.1.0 or latter it breaks at line 45.
