Publish dd-openfeature in PR snapshots

[leoromanovsky]

Motivation

The PR snapshot workflow publishes public, pipeline-specific and branch-specific artifacts for the agent and tracing APIs, but not the standalone OpenFeature provider. Consumers validating provider API changes such as #12387 therefore cannot download a matching immutable dd-openfeature.jar from the PR pipeline.

Changes

• Build :products:feature-flagging:feature-flagging-api:jar in the existing upstream build job.
• Retain the provider JAR for the S3 publication job.
• Publish dd-openfeature.jar under both the branch-specific and pipeline-specific S3 keys.
• Add the immutable provider URL to the Mosaic External Links sidebar.

Decisions

• Extend the existing build and publication jobs rather than add a second pipeline path. This adds one small JAR artifact and upload, without duplicating checkout, dependency download, or polling work.
• Use the stable public filename dd-openfeature.jar, matching the provider artifact name while hiding the changing snapshot version from consumers.
• Keep this PR CI-only; it contains no runtime behavior change.

Validation

• ./gradlew :products:feature-flagging:feature-flagging-api:jar -PskipTests -x spotlessCheck --no-daemon
• git diff --check
• End-to-end proof from Allow telemetry-free OpenFeature providers #12387 pipeline 135263337: dd-gitlab/publish-artifacts-to-s3 passed and both dd-java-agent.jar and dd-openfeature.jar are anonymously downloadable.
• javap against that public provider JAR confirms Provider.Options.telemetryEnabled(boolean) and isTelemetryEnabled() are present. Its SHA-256 is 3ab84365b8b986cac53fcc0d610b5681e8fde44f65e2adbe095e4e89e5b2fa27.

The workflow builds and retains the versioned OpenFeature provider JAR. It publishes the JAR to branch and pipeline S3 keys, and the external link uses the immutable pipeline key.
