Adds build for 1.25.4

It seems I merged too early, sorry for this.
May be I forgot the process.

Should ci/build_module_binaries.sh be updated as well?

I see we want to build for platform: linux/s390x

but there is no image with this platform in https://hub.docker.com/layers/library/nginx/1.25.4/images/sha256-05aa73005987caaed48ea8213696b0df761ccd600d2c53fc0a1a97a180301d71?context=explore&tab=vulnerabilities

May be it is possible to use approach to distribute build for each platform and then ignore if it was failed for some, like it was provided in example?

I don't think we would want to release different architectures, we probably want to wait for docker hub to fix this if it happens in the future.
I was already thinking about changing the build in the PR so that it builds for all platforms all the time, I guess this is giving me the nudge I needed 😄

[miry]

Also make sense. It could parse branch name or PR to run all platforms.
