### New Features

- Add `allow_bone_meal` option to block sources
  - If false, crops that have been fertilized with bone meal will not give skill XP (true by default)
  - Only applies to block sources with `interact` trigger like sweet_berry_bush
  - This reverts default behavior to before 2.3.8
- Support FancyHolograms for damage holograms
  - Must be enabled in config with `hooks.FancyHolograms.enabled`
- Add menu item and template variants
  - Variants are a more powerful version of contexts that can show different items for a single template/item
    based on properties and context filters
  - Variants are defined with a `variants` list of mappings on an item or template
  - Each variant can have the following filtering keys that match an item to a variant:
    - A single `context` or list of `contexts` to filter for templates (if a list, any context can be matched)
    - A `properties` mapping with a set of key-value properties to filter for (if multiple, all properties must be matched)
  - A variant can have the following keys that define the actual item appearance for a given variant:
    - Any keys that define a base item, such as `material`, `key`, and meta keys like `enchantments`
    - A `pos` or `group` and `order`
    - A `display_name` and `lore`
- Allow duplicate of the same template context items using `pos` list
