🟢 Approval recommended

The implementation, documentation, and tests are consistent and correctly expose the requested Go environment values as action outputs without introducing risky behavior changes.

Pull request overview

This PR enhances the actions/setup-go action by exposing a curated set of go env values as step outputs, allowing workflows to reference common Go paths and target information without running extra shell steps.

Changes:

• Add go env -json parsing and export selected Go environment values as action outputs (including a computed go-bin-path fallback).
• Define new output keys in src/constants.ts and document them in action.yml and docs/advanced-usage.md.
• Add unit tests for the new parsing/output behavior and extend CI workflow to print the outputs across OSes.
