The Combining of Elements

 Updated the mod from 1.12.2 to 1.19.4

Additions:
- Added a description to a bottle of thunder.
- Introduced elemental swords as a smithing recipe. On the left, you'll find the netherite sword and on the right, the elemental stone.
- Introduced an upgrade to the flight chestplate. The upgraded chestplate allows the player to fly, in the same manner as in creative mode, while it's equipped.
- Provided a smithing recipe for the upgraded flight chestplate. It's crafted from a flight chestplate combined with a fly stone.
- Added a description to each legendary stone.

Changes:
- The flight chestplate now also imparts slow falling for 5 seconds to prevent fall damage after equipping.
- The name of the "fly chestplate" has been updated to "flight chestplate".
- Updated the recipes for the following items for better balance and logic:
- The combiner now requires a netherite sword instead of a diamond sword.
- The fire stone recipe now uses firecharges instead of lava buckets.
- The water stone recipe now uses blue ice in the four corners instead of lapis blocks and ice.
- The poison stone recipe now uses pufferfish in the four corners, they're really poisonous and easier to obtain than zombie heads and mossy cobblestone.
- The fly stone recipe now needs two less elytras; they've been replaced by two phantom membranes.
- The damage and attack speed of all swords have been adjusted to match the netherite sword plus one extra damage.
- Updated the creative tab icon to the thunder sword, as it needed to be the icon of an existing item, and the combiner was removed.

Bug Fixes:
- Fixed the in-game name of the flight chestplate.
- Corrected the poison sword's incorrect description.
- The thunder sword now has a description.
- The fire sword's description has been improved.
- The water stone's ID, previously "wateer_stone", has been corrected to "water_stone".
- Removed the unintended classification of the air sword as a pickaxe.

Removals:
- The combiner, along with its recipe, has been removed as it was replaced with smithing recipes.
