[BUG] Redhat ubi-micro images aren't supported

[jpinz]

Version of copa

v0.6.2

Expected Behavior

Given the trivy scan report of vulnerabilities, I would expect copa to patch the image

Actual Behavior

Command failed with exit code 1: copa patch -i quay.io/kiali/kiali:v1.77.0 -r /scan-trivy-quay_io_kiali_kiali_v1_77_0.json -t v1.77.0 --debug

Copa currently detects a file which indicates RPM support at /var/lib/rpm/Packages, which in turn makes Copa assume the container isn't distroless. I ran the debugger in GoLand to identify exactly what is happening and have sent my findings to the Copa team.
