fix(alpine) Alpine 3.17 tzdata package doesn't contain zdump anymore

[gounthar]

With the latest (#341 #342 and #343) the tests regarding tzdata failed for Alpine Linux:

jenkinsci.docker.alpine_jdk11.Default.#8 [docker.io/jenkins/agent:alpine] 'tzdata' is correctly installed
jenkinsci.docker.alpine_jdk17.Default.#8 [docker.io/jenkins/agent:alpine-jdk17] 'tzdata' is correctly installed

In the Dockerfile we build the image from eclipse-temurin:11.0.17_8-jdk-alpine. This version now uses Alpine 3.17 and no more 3.16.

In Alpine 3.16 the tzdata package used to contain the zdump binary we're using in our tests.
In Alpine 3.17 it has moved to the tzdata-utils package.

When this is merged, it should allow #341 #342 and #343 to build.
