Mobs with "Silent" tag can still activate sculk sensor

The Bug

When a mob own a "Silent" nbt tag, the mob can't emit sound, but it can still activate sculk sensor.

Steps to Reproduce:

1. Place a sculk sersor
2. Summon a "silent" villager beside the sculk sersor.

   /summon villager ~ ~ ~ {Silent:1}

3. Wait for the villager walk.
   -> The sculk sersor can detect the footsteps of the "silent" villager.

Otherwise, you can set the "Show subtitles" to "ON", then wait for a "silent" mob walk, there isn't "footsteps" subtitles in the bottom right corner, but it can activate sculk sensor, it not usual.
