Issue #3470819 - Fix service definitions for Priority Mail Express 2-Day
Closes #3470819
The service defined in Plugin\Commerce\ShippingMethod\USPS is mislabeled
"_3" = @Translation("Priority Mail Express 2-Day Hold For Pickup"),
The service ID "3" belongs to "Priority Mail Express 2-Day"
"Priority Mail Express 2-Day Hold For Pickup" service ID is "2"
