TLS mutual Authentication with keystore configuration on Linux OS fails to establish a successful connection

### Search before asking

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

### Version

Java Client(2.11.0)-->broker(2.11.0)
Broker instance OS: Amazon Linux 2023
Java App running OS : RHEL and Ubuntu

### Minimal reproduce step

Configure the Pulsar instance for mTLS authentication using Keystore. Then create the Pulsar client using the following sample code.

```java
PulsarClient client = PulsarClient.builder()
.serviceUrl("pulsar+ssl://broker.example.com:6651/")
.useKeyStoreTls(true)
.tlsTrustStorePath("/var/private/tls/client.truststore.jks")
.tlsTrustStorePassword("clientpw")
.allowTlsInsecureConnection(false)
.enableTlsHostnameVerification(false)
.authentication(
"org.apache.pulsar.client.impl.auth.AuthenticationKeyStoreTls",
"keyStoreType:JKS,keyStorePath:/var/private/tls/client.keystore.jks,keyStorePassword:clientpw")
.build();
```

### What did you expect to see?

It should get succeeded with the correct keystore path configuration for Linux.

### Anything else?

As you can observe the debug logs, the keystore path we are providing is not taking into effect and it is being set to null and throwing the file not found error.

**Note**: Same source code is working fine with windows machine.

### Are you willing to submit a PR?

Commencez par KeyStoreSSLContext.createSSLContext (ligne 145) et createClientKeyStoreSslContext (ligne 230), puis suivez la configuration depuis AuthenticationKeyStoreTls jusqu’à NettySSLContextAutoRefreshBuilder.update. Reproduisez la configuration du keystore Linux et vérifiez que les chemins configurés du truststore et du keystore sont utilisés sans la null FileNotFoundException et que la connexion mTLS aboutit.
