feat(Windows): refactor build process by @lemeurherve in https://github.com/jenkinsci/docker/pull/1770
- Switch from a windowsservercore-1809 Temurin base image to a windowsservercore-ltsc2019 Microsoft base image (#1775)
- A proper set of tags is now published, and they include "ltsc2019" instead of only "2019" (#1489)
- A JDK11 image is published again alongside the JDK17 one (#1774)
- As Java 17 is the default JDK, short tags without "jdk" in them are using Java 17 (#1724)
Switch to GA eclipse-temurin:jdk21 images by @lemeurherve in https://github.com/jenkinsci/docker/pull/1738

fix: add additional tags for default Java images by @lemeurherve in https://github.com/jenkinsci/docker/pull/1756
