Send timeout produces an incomprehensible error

[tisonkun]

I change the timeout settings in examples/produce.js to 1 second, and run it without a running Pulsar server. The program failed due to timeout, but the error message is incomprehensible:

[Error: Failed to create producer: TimeOut]

Node.js v19.8.1

I'm wondering if we can throw a clear exception on this case.

[Error: Failed to create producer: TimeOut]

Is it not clear?

@BewareMyPower 🤣 You're right.
