Add Archetype Version to archetype.properties file

[pat-lego]

As a developer, it is important to know which archetype version was used since it impacts the ability to deploy the project to an AEM instance.

Description

Add archetypeVersion to the archetype.properties file

Related Issue

No related issue just something I wanted to add to the project since it was bothering me that it was not already part of the archetype.properties file.

Motivation and Context

I am always documenting the archetype version used in the README but I would much prefer having it in the archetype.properties file since it already contained much of the archetype options that were entered within the project.

How Has This Been Tested?

• Added the variable to the archetype-metadata.xml
• Ran a mvn clean install
• All tests passed
• Created a new project from the SNAPSHOT build that was previously built
• Validated that the archetype.properties file was properly created
