deprecated.json renames translation keys to nonexistent keys

Aligned with massive renames for gamerules, the translation keys gamerule.doFireTick and gamerule.allowFireTicksAwayFromPlayer are renamed to gamerule.minecraft.spread_fire and gamerule.minecraft.spread_fire_far_from_player through deprecated.json. However, these two gamerules have been replaced by fire_spread_radius_around_player, and the two target keys do not exist in the language file. (Nor have they existed.)

Steps to reproduce

1. Check out deprecated.json for the two rename entries aformentioned

2. Check out en_us.json and note that the two target keys are not listed

Or:

1. Start the game

2. Note in the log two rows of warning of the shape [Render thread/WARN] Missing translation key for rename: <old_key>
