Issue description

I have a Lambda function, myFunc, which has been given provisionedConcurrency and is invoked asynchronously via an EventBridge event.

However, while a new version with the alias provisioned gets created for myFunc, the ARN of the EventBridge event doesn't point to the Qualified ARN for the alias (e.g., arn:aws:lambda:aws-region:acct-id:function:myFunc:provisioned) or version (e.g., arn:aws:lambda:aws-region:acct-id:function:myFunc:42), and instead points to the Unqualified ARN (e.g., arn:aws:lambda:aws-region:acct-id:function:myFunc).

Accordingly, the provisioned lambdas do not get utilized.
