minecraft:area_attack requires damage source

Summary:
Previously unneeded, the minecraft:area_attack component now requires a damage source, even with maps version locked to pre-1.20.40

Verification Build:
1.20.40

Regression Builds:
1.20.32

Impact:
Every map we have posted that uses the component, without including the damage source, spams the following error
*minecraft:entity | component_groups | contact_damage | minecraft:area_attack | Damage Source not found: *
This is not a great message to appear for people who have purchased previously unerrored content.

Repro Steps:
1. Download Mob Mechs from store
2. Create template
3. See world spammed with errors regarding minecraft:area_attack
4. Download 100 Days in MC, But
5. Create template
6. See world spammed with errors regarding minecraft:area_attack

Observed Results:
The content log is spammed with errors saying damage source is missing

Expected Results:
No errors should be displayed as content is version locked, and damage source should not be required in the component as the behavior still works as intended in game
