Example biome for comparison:

Seed: -732078047
Coords: 267 64 215

Steps to reproduce:

1. Find lush cave.
   or just use the coordinates and seed above
2. Compare the generation of glowing berries in Java and Bedrock versions.

Observed results:
The generation of glowing berries in the bedrock version is smaller and shorter than in the Java version.

Expected results:
The length and frequency of the glowing berries will be the same in both versions.
