TODO: edit code below

Description:
The below code is trying to atomically send 2 payment from sender to receiver
account by grouping them into an atomic transaction composer.
However, the code is not working. find and fix the bug so that the 2 payments are
successfully sent atomically.

When solved correctly, the console should print out the following:
"The first payment transaction sent 1000000 microAlgos and the second payment transaction sent 2000000 microAlgos"
*/
