Migrate examples to tests_e2e directory structure

- Relocated all files and scripts from `examples` to `tests_e2e` for better organization.
- Updated references and paths in configurations, scripts, and test files.
- Adjusted `bump-version.sh` to handle the new `tests_e2e` structure.
- Updated `.gitignore` to reflect path changes.

+# ==============================================================================
+# EXAMPLE: JWT Validator Plugin
+# ==============================================================================
+#
+# WHAT THIS DEMONSTRATES:
+# - JWT token validation for API protection
+# - RS256 algorithm signature verification
+# - Issuer and audience validation
+# - Public key-based JWT verification
+#
+# REQUIREMENTS (run these first):
+# ```bash
+# # Generate SSL certificates and JWT keys (from project root)
+# cd ../.. && ./tests_e2e/generate-keys.sh && cd tests_e2e/docker
+# ```
+#
+# HOW TO START:
+# ```bash
+# docker compose -f docker-compose-jwt-validator.yml up -d
+# ```
+#
+# HOW TO VERIFY IT'S WORKING:
+# ```bash
+# # Test without token (should fail)
+# curl -k -H "Host: api.local" http://127.0.0.1/
+# # Expected: HTTP 403 - Missing Authorization HTTP header
+#
+# # Generate test JWT at https://jwt.io with:
+# # - Algorithm: RS256
+# # - Payload: {"iss":"https://auth.example.com/","aud":"https://api.example.com","exp":9999999999}
+# # - Paste contents of jwt_private.pem in private key field
+#
+# # Test with valid token
+# TOKEN="eyJhbGc..."  # Replace with your generated token
+# curl -k -H "Host: host1.local" -H "Authorization: Bearer $TOKEN" http://api.local/
+# # Expected: 200 OK with API response
+#
+# # View HAProxy stats
+# # URL: http://localhost:1936
+# # Username: admin
+# # Password: password
+# ```
+#
+# CLEAN UP:
+# ```bash
+# docker compose -f docker-compose-jwt-validator.yml down
+# ```
