Update Calendar Event

//native

/**

 * Update Calendar Event

 * Update an event, or one occurrence of a recurring event when given an occurrence id from List Event Instances. Only the fields you set are changed; `attendees` replaces the whole attendee list, and `start`/`end` are local times in `time_zone`. `extra` takes any other event property (e.g. `recurrence`, `isOnlineMeeting`). Requires Calendars.ReadWrite (a connection default).
