Dead coral plants and fans require Silk Touch pickaxes to be mined, unlike alive variants

The Bug

Only pickaxes enchanted with Silk Touch can harvest dead coral fans/plants, while any tool with Silk Touch can harvest alive coral fans/plants, causing an inconsistency.

Steps to Reproduce

1. Give yourself a pickaxe and axe enchanted with Silk Touch:

   /give @s minecraft:diamond_axe[minecraft:enchantments={silk_touch:1}]
   /give @s minecraft:diamond_pickaxe[minecraft:enchantments={silk_touch:1}]
   

2. Place two alive coral plants/fans and mine each with the axe and pickaxe. Note how they both drop.
3. Place two dead coral plants/fans and mine each with the tools. Note how the dead coral plant/fan only drops when mined with the pickaxe.

Observed Results

The dead coral plant/fan does not drop when mined with the Silk Touch axe.

Expected Results

Dead coral plants/fans would drop when mined with any Silk Touch tool, to match the behavior with alive coral plants/fans.
