Update base image for hashicorp/vault/vault-k8s

Summary

Base image update available for hashicorp/vault/vault-k8s.

If your project's base image is redhat/ubi/ubi8, please update it to use version 8.6. A recent upstream release has caused an issue with 8.5 images, preventing them from running dnf update or dnf upgrade, resulting in broken pipelines.

If this image is a dependency for another other images, after it is merged to master all dependent images will also need to be rebuilt or wait for our nightly, automated rebuild and rescan.
