Fixes issue where split OpenAPI documents could not be bundled back
due to incorrect relative path generation in component $ref references.

**Problem:**
When splitting an OpenAPI document, components that reference other
components (e.g., User schema referencing NotificationPreferences)
would generate incorrect relative paths. This caused bundling to fail
with errors like:
"Cannot resolve: components/schemas/schemas/NotificationPreferences.json"

**Root Cause:**
In writeComponents(), the convertComponentsToRef() function was passed
'components' as currentFileDir instead of the full path 'components/{type}'.
This caused relative path calculation to be incorrect.

**Fix:**
Changed utils/split.js line 63 to pass the correct directory path:
- Before: convertComponentsToRef(..., 'components')
- After: convertComponentsToRef(..., path.join('components', componentType))

**Result:**
- Split documents now generate correct relative paths
- Bundling works correctly for all component references
- All existing tests continue to pass
