subtle bug in the condition (dotnet#42633)

* subtle bug in the condition

subtle bug in the condition used for checking if the store is open within the specified hours.
Ensures that both conditions are checked logically (time must be both greater than or equal to the opening time and less than or equal to the closing time for the store to be considered open)

* update output
