fix (base/ubi10): remove dnf update and shadow-utils reinstall for base UBI 10 Dockerfile

UBI images can contain preinstalled packages that are not reinstallable from
enabled repositories, which causes `dnf reinstall shadow-utils` to fail in
Eclipse Che / OpenShift environments.

Additionally, removing the final `dnf update` avoids pulling inconsistent
package sets during container builds and improves reproducibility across
local and cloud-based development environments.
