consolidate download logic when packaging docker images

**Describe the enhancement:**

`dev-tools/packaging/templates/docker/Dockerfile.tmpl` we have multiple instances where we `apk/microdf update` then add one or two packages then `apk/microdnf clean`. It would be more efficient to build one large list of all the packages that need to be installed and just do one round of update, install, clean.

Open dev-tools/packaging/templates/docker/Dockerfile.tmpl and locate each apk/microdnf update, package installation, and clean sequence. Consolidate the package lists so the template performs one update, install, and clean cycle for the Docker image packaging steps; compare the resulting template with the existing sequences to confirm no packages are omitted.
