maven:3.6-adoptopenjdk-8 not available for Raspberry PI

[nikobockerman]

This PR to docker/official-images https://github.com/docker-library/official-images/pull/9010 removed arm32v7 from Architectures for 3.6.3-adoptopenjdk-8 images.

If I parsed the scripts in this repository correctly, they use same Architectures as adoptopenjdk Docker images. At the time of that PR adoptopenjdk was also lacking arm32v7 architecture for the base image "FROM: adoptopenjdk:8-jdk-hotspot".

But adoptopenjdk has since gotten that architecture back in this PR: https://github.com/docker-library/official-images/pull/9063

Could the official images for maven:3.6-adoptopenjdk-8 image be updated to also contain image for arm32v7?

Currently I could add that one, but other ones are gone Can you use a sha to pull the latest image with arm32v7 ?

Sounds really weird that those Architectures change so often. I would have expected that to happen quite rarely.

I typically update my maven image once a month to get any security fixes etc in to my instance. But I can skip it once now if the arm32v7 will be available next month. I still have the previous image pulled. I'd rather not download directly with hash since I have the tag written in several scripts. So from my part there's nothing urgent that should be done especially if adding arm32v7 now would mean removing support from some other platforms.

I'm hopeful that stability with supported architectures improves in the future, but that is probably depending more on AdoptOpenJdk project than directly on docker-maven project :slightly_smiling_face:
