feat: Enhance Playwright browser caching and CI/CD conditions

- Add Playwright browser caching to i18n-custom-nodes and i18n-node-defs workflows
- Update test-ui.yaml to allow running from feat/add-playwright-browser-caching* branches
- Remove sno-playwright-* from branches-ignore to enable CI for review branches
- Ensure consistent caching strategy across all Playwright workflows

This improves CI performance by avoiding repeated browser downloads and enables
testing from feature branches during development and review.
