fix: enable 1ES internal module proxy for Java dependency resolution

Adds the java.internalModuleProxy feature flag (matching the Go SDK's
golang.internalModuleProxy pattern) to route dependency resolution
through the 1ES internal proxy, bypassing network isolation on the
Azure-Pipelines-1ESPT-ExDShared pool. Also restores image: ubuntu-latest
to match the working Go SDK pipeline configuration.
