[Scheduler] Missing sender, action, and event properties in CreateFormGroupArgs

[yanmariomenev]

Describe the bug When using the edit directive to create a form group the arguments will contain action, dateItem, event, isNew, and mode. However the sender will not be provided, but it is part of the API. Additionally, the API documentation is missing event and action.

To Reproduce Open the following example, edit an event, and check the console - https://stackblitz.com/edit/angular-fuf6rj-gusxgf?file=src%2Fapp%2Fapp.component.ts,package.json

Expected behavior The sender should be provided and add documentation for the missing properties.
