Component minecraft:attack with effect_name doesn't work with minecraft:behavior.delayed_attack

Summary:
Component minecraft:attack with effect_name doesn't work with minecraft:behavior.delayed_attack

Verification Build:
1.16.200, 1.16.220, 1.16.221, 1.17.0.54

Regression Builds:
probably never worked

Impact:
This reduces the overall versatility of the behavior.delayed_attack when compared to the standard minecraft:behavior.melee_attack. This results in unnecessary work arounds and additional development time.

Repro Steps:

1. Download the attached behavior pack
2. start a new world with the behavior pack
3. summon a ravager
4. let it hit you

Observed Results:
player does not get the expected status effect from the attack

Expected Results:
the attack component should be giving all its information to the attack type regardless of it being delayed or not.

Notes:
The behavior in question is:

"minecraft:attack": {
                    "damage": [20,40],
                    "effect_name": "slowness",
                    "effect_duration": 20
                },
