Please add license to enable reuse of the example for our SCA showcases/testing

Hi,
as also mentioned for the other example in jenkins-docs/simple-java-maven-app#955
we would like to re-use your examples for tests and showcases in our OpenChain Automation Workgroup.
Would you be willing to share the examples under an Open Source license (maybe also the others for Python etc.)?
That would save us a lot of time.

Like in the other repo, I already created a PR: #154

Thank you.
