[CI] JNI build is failing when trying to push Docker image

[lidavidm]

Describe the enhancement requested

I think this is because I originally pushed the image myself to bootstrap the build (it takes a very very long time). But it appears that because I did that, the image can only be pushed by me (oops!)

I think I need to ask INFRA to do this: https://docs.github.com/en/packages/learn-github-packages/configuring-a-packages-access-control-and-visibility

I've checked that the workflow has packages:write: https://github.com/apache/arrow-java/actions/runs/12591177348/job/35093904645#step:1:19

I filed INFRA-26404 (requires login)

INFRA corrected the permissions and it seems pushing the image works now.
