All parameters are not working as expected, and typescript definition does not match documentation fully

**Environment Information**
- OS [e.g. Mac, Arch, Windows 10]: Mac
- Node Version [e.g. 8.2.1]: v20.12.0
- NPM Version [e.g. 5.4.2]: 10.5.0
- C++ Toolchain [e.g. Visual Studio, llvm, g++]: g++
- confluent-kafka-javascript version [e.g. 2.3.3]: v1.2.0

**Steps to Reproduce**

- Follow the kafkajs configuration provided and run the code.
- you will see that debug logs are still getting printed, even though logLevel is WARN

**confluent-kafka-javascript Configuration Settings**
```
new KafkaJS.Kafka({
kafkaJS: {
brokers: [envConfig.kafka.bootstrapServers],
clientId: envConfig.serviceName,
ssl: true,
sasl: {
username: envConfig.kafka.saslUsername,
password: envConfig.kafka.saslPassword,
mechanism: 'plain',
},
connectionTimeout: 2000,
requestTimeout: 35000,
authenticationTimeout: 10000,
enforceRequestTimeout: true,
retry: {
initialRetryTime: 300,
maxRetryTime: 30000,
retries: 10,
},
logLevel: KafkaJS.logLevel.WARN,
logger: {
debug(message, extra) {
defaultLogger.debug('message: %s details: %j', message, extra);
},
info(message: string, extra?: object) {
defaultLogger.debug('message: %s details: %j', message, extra);
},
error(message: string, extra?: object) {
defaultLogger.debug('message: %s details: %j', message, extra);
},
warn(message: string, extra?: object) {
defaultLogger.debug('message: %s details: %j', message, extra);
},
namespace() {
return this;
},
setLogLevel() {},
}
},
});
```

**Additional context**

I am migrating from kafkajs to confluent-kafka-javascript.
I was following the documentation - https://github.com/confluentinc/confluent-kafka-javascript/blob/master/MIGRATION.md#kafkajs, but some of the parameters are simply not available or they are not working as expected.

e.g.
logLevel doesn't work.
log_cb have type any, and it's not clear if both params are provided which one will be used. like if I provide Kafkajs.logger and log_cb.
retry.restartOnFailure is not available in ts schema, even though docs say it's available.
