Add the ability to trigger a webhook on the worklog creation event. Docs at https://developer.atlassian.com/jiradev/jira-apis/webhooks say this already exists, but the option is not there in the UI. Attempting to create it via the REST api also fails.

{
  "name": "my first webhook via rest",
  "url": "http://www.example.com/webhooks",
  "events": [
    "worklog_created"
  ],
  "jqlFilter": "Project = SDF AND resolution = Fixed",
  "excludeIssueDetails" : false
}

400 error with Invalid event name 'worklog_created'.
