feat: add Java 8 to the Docker images for running Clouseau

[pgj]

This change makes it possible to run tests that require the Search functionality to be configured. Therefore the test coverage could be increased and issues could be caught with the related applications, such as Dreyfus and the text searches in Mango.

+1 from me.

Would like to get at least a second pair of eyes. cc @nickva @rnewson

[pgj]

Thanks @big-r81 . I will not merge it for now — I have a new approach in mind but that would require changes to the CouchDB code base (the dev/run script itself). I will open a PR about it soon and update this PR according to that one.

[pgj]

With the help of eclipse-temurin the change has become much smaller and it works for all the currently supported platforms.

[rnewson]

I thought the version of scala we need was incompatible with JDK 8, at least at compile time?

[pgj]

Yes, you are right. The compilation of Clouseau does not work with JDK 8. But the created JARs could be run with that version, I have tested it on multiple platforms.

[pgj]

I have extended changes to Debian Bookworm and it was confirmed to be working.

I noticed a failure on s390x architecture:

 => [linux/amd64 internal] load metadata for docker.io/library/eclipse-temurin:11                                                                                                       0.2s

[pgj]

I replaced eclipse-temurin:8-jre for ibm-semeru-runtimes:open-8-jre which has support for s390x. I could test it for linux/arm64 (with Debian Bookworm) and it worked for me.

[nickva]

@pgj good find! This image works so far. I am building/uploading bullseye. Once bullseye finishes I will merge the PR.

[nickva]

+1 building worked on bullseye on all supported architectures

$ ERLANGVERSION=24.3.4.14 ./build.sh buildx-platform debian-bullseye

Excellent. Thanks @nickva !
