JRuby unstable/9.3 development images?

[ivoanjo]

Hello there 👋 !

I work on @DataDog's ddtrace gem, and we use these docker images in CI to test it with JRuby.

It would be nice if, as we get closer to the 9.3 release, development builds were made available as docker images, as it would make adding it to our CI really easy (and thus make sure that we're all clear from the moment 9.3.0.0 hits).

When 9.4 is branched in the future, it would be nice to have unstable images for it as well :)

Hello @ivoanjo, Docker image for 9.3 is already released.

I will keep this issue as a 9.4 to-do, since we would love to have folks be able to try out prerelease images.
