Firehose JRE upgrade to jre8u412 (#42)

Context:
The current image which is being used in the firehose is https://hub.docker.com/layers/library/openjdk/8-jre/images/sha256-a6a74c7b774e00fd2ec5664e257d344f1b7e69e2a618b1c0678f69719863c5ad which is using 8u342 jre.

Problem Statement:
As mentioned in the Kubernetes docs, if the container deployment has to be aware of cgroup v2, we should use jre8u372 or later.
https://kubernetes.io/docs/concepts/architecture/cgroups/#migrating-cgroupv2
https://bugs.openjdk.org/browse/JDK-8230305

Analysis:
OpenJDK HomePage https://hub.docker.com/_/openjdk mentions that these images are for Pre-release / non-production builds.
This image is officially deprecated and all users are recommended to find and use suitable replacements ASAP.
More Details here: docker-library/openjdk#505
Even adoptOpenJDK images are deprecated https://hub.docker.com/_/adoptopenjdk and they recommend to use below trusted community jre/jdk builds

eclipse-temurin: is one of the recommended jre Trusted Community - eclipse-temurin:8u412-b08-jre
This is also used in flink/dagger image

Amazon Corretto - some users have complained about the memory management issues

Solution:
Since we are using the Eclipse Temurin JDK release in Dagger and the Flink community is also using it, we have decided to do the same.
