Lodestone Update Backport

The mod brings back to earlier Minecraft versions all lodestone improvements that were added in the 1.21.5 update.

Key changes:

• Economical crafting - creating lodestone now requires an iron ingot instead of rare netherite
• New lootable item - ruined portal chests may contain one or two lodestones
• Updated achievements - the "Country Lode, Take Me Home" advancement has been moved to the "Adventure" section
• Recipe accessibility - crafting recipe unlocks when obtaining iron instead of netherite

These changes make lodestone a more accessible item in the early stages of the game.
