Replace hard-coded lookup table with on-the-fly version detection

[sormuras]

Overview

Prior to this change, a hard-coded lookup table mapping module names to download URIs was used to resolve the org.junit.start module and all other required modules in junit-source-launcher/lib/DownloadRequiredModules.java.

This change makes use of https://github.com/raphw/jenesis-modules#jenesis-module-repository to resolve modular JAR files via their name@version coordinates; still backed by Maven Central.

Note that org.jspecify needs a pin to its 1.0.0 version due to lack a compiled version in their module descriptor. Find more details here:

• Set module version in compiled module descriptor jspecify/jspecify#746
• Set version in compiled module descriptor. jspecify/jspecify#747

Also note that when a new version of JUnit is released, the index at https://github.com/raphw/jenesis-modules needs to be updated to include the version of JUnit - in order to support it in the junit-source-launcher/lib/DownloadRequiredModules.java program.
