[Parity] Strays without a bow are unable to inflict the slowness effect on players

Strays without a bow don't inflict slowness on the player, unlike Bedrock Edition

How to reproduce:

Java command: /summon stray ~ ~ ~ {}

Alternate commands: /summon stray ~ ~ ~
/item replace entity @e[type=stray] weapon.mainhand with air

Bedrock commands: /summon stray ~ ~ ~
/replaceitem entity @e[type=stray] slot.weapon.mainhand 1 air

Observed behavior:

When a Stray without a bow hits the player, it doesn't inflict the slowness effect

Expected behavior:

A stray without a bow is able to inflict the slowness effect on a player
