Add a starter kit for Java microservice with MicroProfile, Jakarta EE and Open Liberty

**Is your feature request related to a problem? Please describe.**
Currently, the toolkit doesn't include a starter kit for developing Java microservices using open cloud-native Java APIs like MicroProfile or Jakarta EE.

**Which persona(s) does this feature benefit (e.g. developer, SRE, etc)?**
Developers

**What is the impact of not having this feature? What will be the benefit of having this feature?**
MicroProfile and Jakarta EE are open cloud-native Java APIs collaboratively developed by the community under Eclipse Foundation and which IBM is a key contributor and leader. They are gaining momentum and adoption in the industry.

Open Liberty is an all-purpose open-source cloud-native Java runtime that fully supports both MicroProfile and Jakarta EE APIs from IBM that offers leading performance and capabilities for enterprise-grade cloud-native applications.

As a cloud-native toolkit that demonstrates best practices, it is important for the toolkit to includes a starter kit to assist developers and speed up the getting started process to build applications with MicroProfile and Jakarta EE on Open Liberty.
