Motivation
In the Pulsar Dockerfile, amazoncorretto:21-alpine is used as the JDK.
Since Alpine 3.21 has been released, it now contains a JDK built for Alpine 3.21, which might cause compatibility issues.
It's better to use the build that matches the Alpine version used in Pulsar.
Modifications
Use the ALPINE_VERSION argument so that amazoncorretto:21-alpine3.20 image is used, matching the ALPINE_VERSION of Pulsar image.
