fix: resolve GitHub release action failures

- Configure test job to run in test environment (includes test support)
- Configure release job to run in production environment
- Include ex_doc dependency in production for docs generation
- Fix Concord.TestHelper module not available in production builds

Resolves test failures in release workflow where Concord.TestHelper
was undefined due to MIX_ENV=prod excluding test/support files.
