Piglins can only spawn at light level 7 or below

According to https://feedback.minecraft.net/hc/en-us/articles/5992865608205-Minecraft-Beta-Preview-1-19-0-30-31, the max spawn light level of piglins has been adjusted to 11. However, with the spawn light changes of some nether mobs, piglins can only spawn from light level 0 to 7 instead of 0 to 11 in the latest beta/preview version, which may be a wrong change clearly.

Steps to Reproduce:

1. Download, import, and open the attached world in v1.19.60.24 or later version
2. Hold the light block to see light level
3. Wait for few minutes

Observed Results:
Piglins only spawn at light level 7 and never spawn at 8.

Expected Results:
Piglins should spawn at both light level 7 and 8.
