Adds scorecard workflow to publish OpenSSF scores (#3163)

Publish OpenSSF Scorecard results, which means users and downstream
consumers can easily discover the project’s security best-practice
signals via Scorecard API.

Publishing Scorecard results:

- Improves transparency for users and integrators
- Provides early visibility into missing or improvable security
practices

Fixes #3162
