Updated script to pull Portainer's exact release

Adjusted the Portainer container setup script to fetch the latest release tag from GitHub and use this specific tag when pulling the image. This ensures the container is set up with the correct Portainer version, avoiding inconsistencies that occur with the ':latest' tag. Removed redundant digest-based image version check for clarity and efficiency. The script now reliably pulls and runs the most recent Portainer release version.

Fixes issues with outdated container versions when using ':latest' tag.
