Latest alpine based images using 3.9 alpine repo instead of 3.18

Jenkins and plugins versions report

What Operating System are you using (both controller, and any agents involved in the problem)?

Official jenkins:2.419-alpine

Reproduction steps

1. Pull image anywhere from "jenkins:2.409-alpine" to "jenkins:2.419-alpine" (According to tags this is using alpine tag 3.18.3 as base)
2. cat /etc/apk/repositories

Expected Results

Expect to see 3.18 repo being used

Actual Results

3.9 alpine repo is being used

Anything else?

I might be misunderstanding something here but it seems that if the image is using alpine 3.18.3 as its base it should use the 3.18 repo, this is validated by pulling the 3.18.3 alpine image directly and checking on that or by building the Jenkins alpine dockerfile locally

@timja are you sure? This is using an older pinned tag not the lts

It is probably the same root cause, cc @dduportal
