Describe the feature

Allow Categories to be locked using advancements, the same way the entries and pages can be locked. If Inheritable Advancement Locks (#290) is also added, allow categories to be parents of other categories, and entries/pages in other categories.

Additional context

Usecase: Having an entry about every biome and separating them into categories by dimension. Lock the Nether Biomes Category behind the "Enter the Nether" advancement so that all the nether biomes unlock together without having to add the advancement line to every entry.
