Issue:
Webhook type for repository edits is missing default branch
Repository edit events can include default branch changes and are dropped during parsing because it's missing from the types. (https://docs.github.com/en/webhooks/webhook-events-and-payloads?actionType=edited#repository)

```json
{
  "action": "edited",
  "changes": {"default_branch": {"from": "master"}},
  "enterprise": {
    "description": "...",
    "id": 1,
    "name": "Inc"
  },
  "organization": {
    "id": 1,
    "login": "Inc"
  },
  "repository": {
    "id": 1,
    "name": "repo",
    "full_name": "Owner/repo",
    "owner": {},
    "default_branch": "main"
  },
  "sender": {
    "id": 1,
    "login": "user"
  }
}
```
