Request to add newest 1.11.x images

[simsurace]

There seem to be no Docker images for 1.11.8 and 1.11.9 on dockerhub https://hub.docker.com/_/julia/tags?name=1.11.9 and 1.11 still refers to 1.11.7. Julia 1.11 might be a bit unusual here since it receives updates even though it is not LTS nor the current release, but for this same reason (some stuff is not easily updated to 1.12) it would be nice to have all versions available.

Thanks for the notice. I guess we removed it prematurely under the assumption that 1.11.x was end of life. I've opened a PR to add it back: #103.

Awesome, thanks!
