Description of Changes

Remove publishing OpenSSF Scorecard results and the badge from main README.md.
This change is needed, because currently, the scorecard action fails with an error:

workflow verification failed: workflow verification failed: scorecard job must only have steps with uses, see: https://github.com/ossf/scorecard-action#workflow-restrictions for details.

Which is caused by our manual filtering of the false positives introduced in commit: a7d4367.

To fix the scorecard action we have to either:

(1) stop publishing the scorecard action results, and thus also remove the OpenSSF badge or

(2) revert the commit a7d4367. The downside here is that we would then have to manually keep dismissing the false alerts on Dangerous-Workflow on the Github code scanning dashboard.

This PR implements above option (1).
@brianmcgillion: let me know If you prefer (2) instead, and I'll close this PR and open a new one to revert a7d4367.
