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: Portainer Behind EasyHAProxy (Swarm)
-# ==============================================================================
-#
-# WHAT THIS DEMONSTRATES:
-# - Running Portainer management UI in Swarm mode
-# - Service discovery with EasyHAProxy
-# - Using persistent volumes for Portainer data
-#
-# REQUIREMENTS (run these first):
-# ```bash
-# # Ensure EasyHAProxy is deployed
-# docker stack deploy -c easyhaproxy.yml easyhaproxy
-#
-# # Add to /etc/hosts (idempotent)
-# grep -q "portainer.local" /etc/hosts || echo "127.0.0.1 portainer.local" | sudo tee -a /etc/hosts
-# ```
-#
-# HOW TO START:
-# ```bash
-# docker stack deploy -c portainer.yml portainer
-# ```
-#
-# HOW TO VERIFY IT'S WORKING:
-# ```bash
-# # Check service is running
-# docker service ls | grep portainer
-# # Expected: portainer_portainer with 1/1 replicas
-#
-# # Access Portainer
-# curl http://portainer.local
-# # Or open in browser: http://portainer.local
-# # First time: Create admin user
-# ```
-#
-# CLEAN UP:
-# ```bash
-# docker stack rm portainer
-# # To also remove data volume:
-# # docker volume rm portainer_portainer_data
-# ```
-#
