DNF5's install command does not upgrade the version of already-installed packages. Azure Linux 4 base images can contain an outdated ca-certificates package that trusts the compromised eMudhra certificate chain.

This PR uses a single DNF5 transaction to install .NET dependencies and explicitly upgrade ca-certificates in regular Azure Linux 4 runtime-deps images.
Distroless images are not affected.

Refresh the four internal runtime-deps snapshots to match the DNF5 install and CA certificate upgrade transaction.
