client.certReload documentation discrepancy in ZooKeeper 3.8.1 and 3.7.2

[Description] There is a discrepancy between the documentation and the actual codebase in ZooKeeper releases 3.8.1 and 3.7.2 regarding the availability of the client.certReload feature. The documentation states that the client.certReload functionality is available in these versions, but upon thorough code review, it has been found that this feature does not exist in the mentioned releases.

https://github.com/apache/zookeeper/blob/688c69c19dc64836e91dc9ae97aeaeaf462f0556/zookeeper-docs/src/main/resources/markdown/zookeeperAdmin.md?plain=1#L1782

[Issue] However, the discrepancy between the documentation and the codebase indicates that the client.certReload feature is missing in the 3.8.1 and 3.7.2 releases.
Here is the master where the code is available: https://github.com/apache/zookeeper/blob/688c69c19dc64836e91dc9ae97aeaeaf462f0556/zookeeper-server/src/main/java/org/apache/zookeeper/server/NettyServerCnxnFactory.java#L123
 
And here on the 3.8.1 release it is not available:
