Vexes' hitboxes aren't vertically centered with their models

The Bug:

Vexes' hitboxes aren't vertically centered with their models.

In 22w45a, the model of vexes was changed but their hitboxes remained the same to allow vexes to be easier to fight. While this is okay, one would expect the hitbox to be centered with the entity's model which is currently not the case.

Steps to Reproduce:

• Summon a vex with its "NoAI" tag set to "1b".

• /summon minecraft:vex ~ ~1 ~ {NoAI:1b}

• Enable entity hitboxes by pressing F3 + B.
• Observe the hitbox of the vex closely.
• Take note as to whether or not vexes' hitboxes are vertically centered with their models.

Observed Behavior:

Vexes' hitboxes aren't vertically centered with their models.

Expected Behavior:

Vexes' hitboxes would be vertically centered with their models.
