[fix][sql] Remove useless configuration for Pulsar SQL

[gaoran10]

Motivation

In PR #14506, we remove the useless config managedLedgerNumWorkerThreads
but we didn't remove the config from the config file, if users use this configuration, the Pulsar SQL can't startup due to strictConfig mode, remove this useless configuration for Pulsar SQL.

// at this point all config file properties should be used
// so we can calculate the unused properties
unusedProperties.keySet().removeAll(configurationFactory.getUsedProperties());

for (String key : unusedProperties.keySet()) {
    Message message = new Message(format("Configuration property '%s' was not used", key));
    (strictConfig ? errors : warnings).add(message);
}

// If there are configuration errors, fail-fast to keep output clean
if (!errors.isEmpty()) {
    throw new ApplicationConfigurationException(errors, warnings);
}

Modifications

Remove useless configuration pulsar.managed-ledger-num-worker-threads from the config file.
