Add Ant-wrapper to junit5-jupiter-starter-ant

[sormuras]

Overview

The junit5-jupiter-starter-ant build process relies on pre install actions executed by its build.sh. These actions are:

• Load and extract Ant binary distro from Apache mirror to the local workspace.
• Load and store junit-platform-console-standalone jar in local ant installation.
• Call ant with default test task.

The first two steps need to be replaced with Ant Wrapper feature.

Deliverables

• [ ] Add some antw support and make sure everythings builds fine.
• [ ] Include junit5-jupiter-starter-ant in build-all-samples program.

@sormuras I've forked this sample junit5-jupiter-starter-ant and was able to get through the Junit5 test but when I try to run Junit4 test , the console o/p prints 0tests for Junit4.

Could you please comment if you have tried that

How did you try to run a JUnit 4 test? Please share more details in a new issue. Thanks.
