dbo.Broadcaster "LastUpdated" Column Hasn't Been Properly Implemented

No update is being applied to the "LastUpdated" column. Remember to use UTC time.

Look into writing an `UPDATE TRIGGER` from the SQL side.

```sql
CREATE TRIGGER BroadcasterLastUpdated ON dbo.Broadcaster
AFTER UPDATE
AS
BEGIN
    UPDATE dbo.Broadcaster 
    SET LastUpdated = GETUTCDATE()
    FROM dbo.Broadcaster b
    INNER JOIN inserted i
        ON b.Id = i.Id
END
GO
```
