The `./modules` directory contains files that are no longer included in assemblies. 

We should identify these files, perhaps by using a script, and then move these files to a new directory named `/archive`.

Examples mentioned in https://gitlab.cee.redhat.com/quarkus-documentation/quarkus/-/merge_requests/799 include:

• modules/proc_deploy-container-image-quarkus-native.adoc
• modules/proc_deploy-serverless-quarkus-java-app-openshift-extension.adoc
• modules/proc_using-openshfit-extension.adoc
