[Webhooks](https://docs.gitlab.com/ee/user/project/integrations/webhooks.html) contain a JSON payload.
One of its elements is `project`.
I would expect the JSON object below the `project` key to be consistent across all webhooks of a given project, be it `push` or `pipeline`.
Currently, `homepage` or `ssh_url` (among other) are not available for all hook events (eg: `pipeline`).
Shouldn't this be made more consistent?
