[fix](memory) fix ThreadPoolExecutor leak in PublishVersionDaemon (#60720)
publishExecutors is a static field, but the constructor appends new
thread pools on every invocation without checking if they already exist.
The constructor is called each time a new Env instance is created, which
happens periodically during Env checkpoint/journal replay (the
checkpoint thread creates a new Env to replay the journal). Each call
appends publish_thread_pool_num (default 128) pools to the static list,
causing unbounded growth.
