fix: set up JDK 17 in SCA scan workflow

The Snyk Gradle scan job was failing with "Unsupported class file major
version 69" because no JDK was configured, so Gradle fell back to
whatever Java the runner defaults to. Explicitly set up JDK 17 to match
the project's sourceCompatibility and the JDK used in publish-release.yml.
