[Bug] Getting ConnectError when expecting AuthenticationError

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.

### Version

pulsar-all image version 2.10.32 and pulsar-all image version 2.11.0
Token auth enabled
Python client version 2.10.1

### Minimal reproduce step

Token auth is correctly set up and tested to be working with a good token.

Again, with token auth enabled, try to connect with a (python) client and provide a broken token (try various ways to break it, including a malformed token).

I tried this with a standard token mechanism, but I also tried this with a custom Auth plugin where other token fields can be broken in similar ways.

### What did you expect to see?

Expect a ConnectError when there are network reasons for not being able to establish connection.

Expect an AuthenticationError with a well-formed token without permission to use Pulsar resources.

Expect an AuthenticationError when there is a bad token; but get ConnectError.

We got reports from users that ConnectError was confusing when debugging issues.

### What did you see instead?

ConnectError when a bad token is provided.
```
bad_admin_token = "eyJhbGciOiJIUzI1aaaaaaaNiJ9.eyJzdWIiOiJhZG1pbiJ9.1Eu3ph4RneevmKIKlE9gglAAyFBJMeN7GM-ZnHLZNsM" # ConnectError
pulsar_service_url = 'pulsar://localhost:6650/'
client = pulsar.Client(pulsar_service_url, authentication=pulsar.AuthenticationToken(bad_admin_token))

try:
producer = client.create_producer('my-topic')
for i in range(10):
producer.send(('Hello-%d' % i).encode('utf-8'))
client.close()
except Exception as e:
print(e.args)
print(dir(e))
print()
raise
```
Get this result:
```

```

Again, our users complain that this error is hard to debug in logs because it would have you troubleshoot connectivity rather than problems with authentication setup.

### Anything else?

I have tested this with both an admin token and lesser permissions tokens.
I have also tested breaking the token in various parts that would fail to parse it.
Also tested against a custom Auth plugin where we implement token checks.

### Are you willing to submit a PR?

- [ ] I'm willing to submit a PR!

Empieza reproduciendo el caso de un token mal formado con el cliente de Python contra las versiones del servicio Pulsar descritas y, después, sigue el manejo de los fallos de autenticación del cliente C++. Se considera terminado cuando los tokens mal formados o no autorizados se manifiestan como AuthenticationError, mientras que los fallos de red siguen manifestándose como ConnectError.
