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: FastCGI Plugin with PHP-FPM
+# ==============================================================================
+#
+# WHAT THIS DEMONSTRATES:
+# - PHP-FPM configuration with FastCGI protocol (proto: fcgi)
+# - FastCGI plugin for PHP environment variable configuration
+# - TCP connection to PHP-FPM on port 9000
+# - PATH_INFO support for RESTful routing
+# - Custom document root and index file configuration
+#
+#
+# HOW TO START:
+# ```bash
+# docker compose -f docker-compose-php-fpm.yml up -d
+# ```
+#
+# HOW TO VERIFY IT'S WORKING:
+# ```bash
+# # Test main page
+# curl -k -H "Host: phpapp.local"  http://127.0.0.1/
+# # Expected: 200 OK with PHP environment info
+#
+# # Test PHP info page
+# -k -H "Host: phpapp.local"  http://127.0.0.1/info.php
+# # Expected: phpinfo() output
+#
+# # Test PATH_INFO routing
+# -k -H "Host: phpapp.local"  http://127.0.0.1/test-path-info.php/users/123
+# # Expected: PATH_INFO=/users/123
+#
+# # View HAProxy stats
+# # URL: http://localhost:1936
+# # Username: admin
+# # Password: password
+# ```
+#
+# CLEAN UP:
+# ```bash
+# docker compose -f docker-compose-php-fpm.yml down
+# ```
+#
