.sync/azure_pipelines: Switch from microdnf to dnf (#115)

The following commit in tianocore/containers switched from `microdnf`
to `dnf` since `microdnf` is no longer available in the Fedora 35
minimal base image.

tianocore/containers@3487a34

Therefore, `microdnf` will currently fail (not found). This change
updates code using the Fedora 35 container image to switch to `dnf`.
