Not using braces will cause a fatal error in context ArrayData

During a NotifyUsersWorkflowAction, if you use $Context.LinkToPendingItems rather than {$Context.LinkToPendingItems} you will get an error saying forTemplate() doesn't exist on ArrayData. Adding the braces fixes this.

Using braces is the suggested way to do it and can be seen in the help toggle area as well, but if it's that easy to cause a system error, perhaps we should handle it somehow and return a friendlier error like "Failed to parse your content message - please check your syntax, see the help area for more info" etc
