BAEL-5540: Sending Soap Request via Postman (#12581)

* fix(build): remove jaxb2-maven-plugin plugin

XCJ fails due to unresolved/conflicting  dependencies. The project runs fine without jaxb2-maven-plugin plugin, given maven-jaxb2-plugin is already there.

* fix(build): correct gen files imports

maven-jaxb2-plugin generates in  com.baeldung.springsoap.client.gen, not com.baeldung.springsoap.gen

* chore: add postman collection

* revert: set back jaxb2-maven-plugin

Didn't run project with Java 1.8, that's why I was facing build errors
