Add maxLevel to enchants.json and minor updates

Sorry for wasting your time with the prior PR. I thought ill just open an Issue too properly share my idea and I can make another quality PR if you agree:

I want to add a way of obtaining the maxLevel of an item (any means) from the repo. I have 2 ideas for this:

Idea 1: Updating enchants_xp_cost then using its lenght

To do this we'd update enchants_xp_cost to the values of the Combining Costs* table on the offiicial Wiki.
Example of an already correct entry in the dict: habanero_tactics": [ 0, 0, 0, 250, 300 ],
Currently some enchantments (for example: "the_one": [ 250, 300 ],) do not have "leading" zeros as placeholders. Currently none enchantments have "trailing" zeros ("efficiency": [ 10, 15, 20, 25, 30, 0, 0, 0, 0, 0 ],)

Example usage in Firmament: RepoManager.enchantData.allEnchants?.enchantExperienceCost?.mapValues { it.value.size }?: emptyMap() (RepoManager is a object which gets data from this repo)

*The Combining Cost dict is called enchants_xp_cost in the json, but also provides combining costs for non E-Table enchants. This is confusing, as not every combining cost equals the enchanting cost

Idea 2: Add a "maxLevel" key that has the same structure as "max_xp_table_levels"

(should be obvious)

The cleanest would probably to add the first for consistency and the second for intuitive usage.

I also found outdated data in the file:

Missing in enchants_xp_cost:
https://wiki.hypixel.net/Green_Thumb_Enchantment

Outdated enchants_xp_cost :
https://wiki.hypixel.net/Impaling_Enchantment
https://hypixel-skyblock.fandom.com/wiki/Divine_Gift

Missing in max_xp_table_levels:
aiming, blessing, fire_aspect, flame, impaling, knockback, piercing, punch, rainbow, snipe

Missing in enchants:
SHEARS

Missing in enchant_pools (probably/maybe not complete):
Axe Ultimate Enchants, The new Turbo Books, One for all with Champion and Divine Gift

Start by inspecting enchants.json, especially enchants_xp_cost, max_xp_table_levels, enchants, and enchant_pools, then compare the listed missing or outdated entries with the linked wiki pages. Confirm which max-level representation maintainers want before editing. Done means the chosen max-level data is consistent and all listed missing or outdated entries are reviewed and updated.
