Add third Elder to Fray's End #1101

Place a third Elder into Fray's End, whose storybook only contains the template quest; and make the StoryQuest Elder not offer that quest.

(If the artwork from #1100 is not yet ready, reuse the sprite sheet for one of the existing elders. If the dialogue from #1102 is not yet ready, use the existing story_quest_starter.dialogue.)

This will require a bit of programming and/or reorganisation to hide the template quest from the StoryQuest Elder, and only show the template quest in the new Template Elder. I think the cleanest approach would be to create a new folder, scenes/quests/template_quests, and move the scenes/quests/story_quests/NO_EDIT folder to scenes/quests/template_quests/NO_EDIT. Then the new Template Elder's Quest Directory property would be set to res://scenes/quests/template_quests. addons/storyquest_bootstrap/copier.gd would need to be updated for this reorganisation.

For the time being, the new elder can be placed in some empty space in the map, perhaps to the top-right of the StoryQuest Elder.
