Webhook pipeline triggers can't process requests with specific Content-Types
### Summary
I use contentful.com as headless CMS and want to trigger a build of my Jekyll project, when content is updated. That worked until recently. Now I get the error message:
```
[...]
"statusCode": 406,
"body": "{\"error\":\"The requested content-type 'application/vnd.contentful.management.v1+json' is not supported.\"}"
[...]
```
### Steps to reproduce
1. Create an account with contentful.com
2. Setup a webhook for the project
3. Add webhook like: https://gitlab.com/api/v4/projects/PROJECT_ID/ref/master/trigger/pipeline?token=TOKEN
4. Check the failing Webhook calls when you update a piece of content
### What is the current *bug* behavior?
Gitlab.com rejects the webhook call which looks like this:
```

```
### What is the expected *correct* behavior?
I guess the idea of the Content-Type `application/vnd.contentful.management.v1+json` is that it would be processed as `application/json`.
This is their documentation on the matter: https://www.contentful.com/developers/docs/references/content-management-api/#/reference/webhooks
### Output of checks
This bug happens on GitLab.com
Any help on this would be much appreciated!
