Fix inverted matrix logic in CI workflows

CRITICAL FIX: The determine-matrix logic was backwards.

Before:
- master/force_run/full-ci → ["latest"] (only 1 config)
- Regular PRs → ["latest","minimum"] (both configs)

After (correct):
- master/force_run/full-ci → ["latest","minimum"] (both configs)
- Regular PRs → ["latest"] (only 1 config)

This ensures:
- PRs get fast feedback with latest dependencies only
- Master and full CI runs test both latest AND minimum supported versions

Affected workflows:
- examples.yml
- gem-tests.yml
- integration-tests.yml
- package-js-tests.yml
