Hitbox nether sprouts is not centered and not the same as in Java

This bug report is a parity issue with Java.

Summary:
In the Java version, the nether sprouts have a hitbox that is always centered. And also in the Java version the hitbox is much smaller.
Java: 3 pixels high and 12 pixels on the sides (2 pixels off the edge).
Bedrock: 5 pixels high and 11 pixels on the sides.

Steps to reproduce:

1. Place nether sprouts.
2. Take a look at the dimensions of the hitbox.

Observed results:
The hitbox is not always in the center, and also has dimensions that do not correspond to the Java version.

Expected results:
The hitbox of the blocks must be the same.
