[1.12.28] - 2024-08-15

Added

• an unattended setup option for installing the Venice REPL.
  This allows for automated setups or unit testing the setup.

Changed

• the Gradle shadow plugin.
  The Gradle plugin "io.github.goooler.shadow" has been retired now as well.
  Migrated to "com.gradleup.shadow" (see https://github.com/GradleUp/shadow).
  This seems to be the final new home for the retired
  "com.github.johnrengelman.shadow" plugin.
• the Gradle CI workflow to build and test on Ubuntu and Windows using
  JDK 8, 17 and 21.
