[BUG] Snapshot build is broken

[dblock]

Describe the bug

Coming from opensearch-project/opensearch-build#189, attempting to build a snapshot version of this plugin:

./gradlew assemble --no-daemon --refresh-dependencies -DskipTests=true -Dopensearch.version=1.0.0-SNAPSHOT -Dbuild.snapshot=true

Fails to find the non-snapshot depenency. It should be looking for the snapshot dependency of OpenSearch.

To honour the JVM settings for this build a new JVM will be forked. Please consider using the daemon: https://docs.gradle.org/6.7/userguide/gradle_daemon.html.
Daemon will be stopped at the end of the build stopping after processing

Expected behavior
Build to pickup snapshot version of OpenSearch and jobscheduler/spi.
