JAVA_PUBLIC_SHADOW projects aren't in the bom, and get an unnecessary classifier added

[niloc132]

The psk auth plugin is deployed to maven central, as a PUBLIC project, but doesn't appear in the bom

https://search.maven.org/artifact/io.deephaven/deephaven-bom/0.34.3/pom

The deephaven-server project explicitly depends on it in gradle, and the pom appears to depend on it:

https://search.maven.org/artifact/io.deephaven/deephaven-server/0.34.3/pom

However, Gradle deploys the psk dependency to central as packaging=pom, and classifier=all to get the jar itself. This means that the deephaven-server dependency will not have the psk present at runtime as specfied, when loaded from maven central, though it will correctly have it when run from the deephaven-core project itself.
