fix: use correct environment URLs based on branch in CI tests

- Update test-site-builds.yml to dynamically set ENV based on branch
- dev branch now uses 'dev' environment (jonphipps.github.io URLs)
- main branch uses 'production' environment (www.iflastandards.info URLs)
- Ensures CI tests validate the correct environment-specific URLs
