test: Implementation to handle changed format for .node folder from X.Y.Z-<tag> to X.Y.Z

Updated startup-localenv-with-data.sh to handle the format change in .node directory structure:
- Previously: .node/X.Y.Z-<tag>/ (e.g., .node/0.18.0-rc.11/)
- Now: .node/X.Y.Z/ (e.g., .node/0.18.0/)

Implementation details:
- Extract base version (X.Y.Z) from NODE_TAG by removing tag suffix
- Prioritize new format (.node/X.Y.Z/) first
- Fallback to old format (.node/X.Y.Z-<tag>/) for backward compatibility
- Provide clear error messages if neither format exists

Tested scenarios:
- NODE_TAG=0.18.0 → Uses .node/0.18.0/ (new format) ✓
- NODE_TAG=0.18.0-rc.11 → Uses .node/0.18.0/ (new format preferred) ✓
- Maintains backward compatibility with old format directories
