Utilise latest openjdk release in image runtime #237
Description
Currently our images are based upon ubi9/openjdk-21-runtime which is an LTS release. Instead we should utilise the latest available JDK version so that we can take advantage of the latest performance enhancements.
Implementation Ideas
We should migrate away from ubi9/openjdk-21-runtime and utilise ubi9/ubi-minimal as the runtime image. This allows us to then enable the EPEL repositories and manually install the latest available JDK via microdnf.
