Replace hardcoded bazel-selenium references with dynamic path resolution (#16976)

* Replace hardcoded bazel-selenium references with dynamic path resolution

* Validate bazel output_base before constructing external path

* Fix EXEC_ROOT path resolution by following symlink before navigating

* Use bazel info execution_root for reliable path resolution

* Keep bazel-selenium in README for readability
