Ruler just like other heroic spirit are merely a hero who got their name recorded on the throne of heroes. Do note that by default those on Throne of Heroes are not sorted by their class but rather a complete form of their legend.

To be summoned as Ruler however require certain requirement to be met by the heroic spirit. the first one is that the absence of wish to the holy grail, and 2nd is that at some point in their life they need to be guided by the will of God (in Nasuverse case it's the will of Gaia), and generally need to be the Lawful-Good type in contrast to Avenger evil alignment. the class Ruler however does not exist in the original "Station of Crown" (Grand) system which is the prototype of HGW in Fuyuki as such it's original vessel made by Einzbern alongside the Avenger class vessel.

However, again the lore in Apocrypha being a mess it is, turns out the Ruler in that war actually have a reason to seek the grail.. In other word either the basic premise of "not having the wish nor motivation to seek the grail" is not true,, or the mechanism are not failsafe.. or it's just another Apocrypha episode of whatever goes for the plot.

Basically Jeanne exploit has been recorded and she's ascended to the throne of heroes, however she's among the heroic spirit that does have any reason to seek the grail nor participate in the war, hence unable to be summoned as servant in Fuyuki HGW. (Yes, case like this does exist, only servant that have wishes will answer to summon but oddity like Jeanne, or Tamamo that care jack shit about the grail nor actually want to fight does exist)
