[shaykeren]

This PR fixes the Bootstrap resource path mismatch in the Spring PetClinic application.

Changes made:

1. Updated Bootstrap JS path to match NPM WebJar structure:
   • From: /webjars/bootstrap/5.2.3/dist/js/bootstrap.bundle.min.js
   • To: /webjars/bootstrap/js/bootstrap.bundle.min.js
2. Added Bootstrap CSS path using the correct NPM WebJar structure:
   • Added: /webjars/bootstrap/css/bootstrap.min.css

This fix ensures that Bootstrap resources are properly loaded from the NPM WebJar package.
