Content Published webhook on Multicultural site results in wrong payload or null

[DeadMonkeyX]

Which Umbraco version are you using? (Please write the exact version, example: 10.1.0)

15.2.0

Bug summary

When publishing content in the non-default culture the webhook payload is either the expected payload for the default culture or null

Specifics

No response

Steps to reproduce

1. Do a clean installation of v. 15.2.0
2. Setup a doctype with some content fields:
   

2.1 that has Allow vary by culture

2.2 I have also set this doctype to Allow at root

3. Add another language and make sure it is not the default language (I used Spanish in my testing)

4. Setup webhook using webhook.site for testing

5. Create a new content item using the doctype from step 2 and save and publish this

5.1 Check webhook response and it looks fine

6. Add the same page but in Spanish, save and publish

6.1 Check webhook response and this is the "wrong" response

Expected result / actual result

I expect to get the content publish response from the Spanish page, However, I'm getting the English one (see steps to reproduce)

I have also experienced getting a null in the webhook payload, but I cannot consistently reproduce that behavior
