Rephrase Qt plugin names on Maven

Under the Maven repository of Qt plugins https://mvnrepository.com/artifact/org.qtproject.qt, I've noticed few wording issues that need to be fixed.

For the Group:

"Qtproject" and "Qtproject Qt"-> "Qt Project"

that would look better if it's simply "Qt Project" and for the company (if there's such a field) it could be "Qt Group".

same for plugins

"QtJenny" -> "Qt Jenny" or "QtJenny"

"Qtproject Qt GradlePlugin" -> "Qt Gradle Plugin"

"Qtjenny Annotation" the description could mention it's the annotations and not the generator itself.
