Was Ahch-To such a mystery?
In Star Wars: The Last Jedi, we see that Ahch-To is where Luke was hiding and the same place
has the ancient Jedi temple. Also, while showing the tree branch shelf to Rey, he says that this was built many many years ago just for the purpose of storing the ancient Jedi texts.
Considering all this, wouldn't the other members of the force (Leia, Maz Kanata, Kylo Ren etc) know that Ahch-To could have possibly been where Luke is hiding? Instead of going to the trouble of hiding/finding the map to his location, couldn’t the Resistance or The First Order just send out their army on a hunt
to the historic Jedi planet?

The legend of "The First Jedi Temple" was probably known to all (trained) Jedi, but at that point, Luke was the only Jedi left.
And even Luke didn't know where it was exactly.
Han says this in Episode VII: The Force Awakens:
People that knew him best think he went looking for the First Jedi Temple.
The "went looking" part implies that Luke had an idea where to start, but didn't know it's exact location.
You mention a few specific people:
Leia is force-sensitive, but was never "trained" as a Jedi.
Maz is old and wise, and claims to know the Force (she is considered "Force-sensitive"), but she definitely doesn't claim to be a Jedi, or to have been trained in the force in any official capacity.
Kylo Ren was trained by Luke, who might have told him about The First Jedi Temple, but since he didn't know its exact location, he wouldn't have been able to tell Kylo Ren.
