Fix XTS quickstart to compile WFLY 20 quickstarts correctly

The current XTS quickstart (https://github.com/jbosstm/quickstart/tree/5.10.5.Final/XTS) fails because there is used WFLY 20 quickstarts which was changed and start providing a microprofile quickstart which expects microprofile dependencies to be defined.

The XTS quickstarts need to add `version.microprofile.bom` property to compile correctly.
