Add Application molecule tests in GitActions

[sownak]

Description

As a developer I want to run all Example application Molecule test Scenarios so that the Git Actions flow is complete for Applications. Add a condition so that the Application tests are run only when the check-in has a "[application]" in the commit message

Acceptance Criteria

1. GitActions test should run for Sample applications when commit message has "[application]"
2. All Application molecule test scenarios should be run for both supplychain and identity. (this can be separated if the tests take more than 5 minutes to run)
3. Tests should run parallelly for supplychain and identity app
