[MCPE-122488] Polar bears killed by fire/lava does not drop cooked fish

When you kill a polar bear with lava or fire aspect sword, it does not drop cooked fish, but instead raw fish. This bug is fixed in the next Java snapshot. (~~MC-102269~~)

Step to Reproduce
1. Spawn a polar bear (preferably an adult one, baby doesn't drop anything)
2. Get a sword enchanted with fire aspect or a bucket of lava
3. Kill the polar bear.
---> It drops raw cod/salmon, instead of cooked one.

The Fix
In polar_bear.json file in the loot_table/entities folder, you can add these functions to get the cooked one:
