ci: Update TypeScript CI workflow to select tests if test files change (#4840)

* Update TypeScript CI workflow: streamline suite selection and dependency setup

- Set default test suites to an empty array to dynamically determine suites based on changes.
- Ensure compact JSON output for test suites.
- Simplify Node.js and Playwright setup by using built-in caching and custom actions.
- Add UV_CACHE_DIR environment variable for caching.

* Expand test coverage paths in changes-filter.yaml configuration
