Llama aggression range has decreased significantly

Llama and Trader Llama aggression range towards a target decreased significantly from 8 - 9 blocks down to 3 - 4 blocks.

1. This affects 1.21.2 and up according to my knowledge.

2. Existing Llamas from an older version that are brought to the newer versions remain unaffected.

3. This change is undocumented which convinces me it's a bug.

Steps to reproduce:

In 1.21.0 and below:

• Replicate the setup in the "1.21.0 setup.png" where the wolf is 8 blocks away from the llama.

• Observe the llama attack the wolf (if it does not work, replace the llama, their range varies slightly but it should not take more than 5).

In 1.21.3 and above:

• Replicate the setup in the "1.21.0 setup.png" with a newly spawned llama.

• Notice no llama notices and attacks the wolf, cycling through 40 llamas did not change this outcome.

• You will have to reduce the distance between the llama and wolf as in the "1.21.3 setup.png" for the llama to attack the wolf.

• You can update the 1.21.0 world and notice the existing llama still has the longer range.
