chore: update ingress configurations

- Enable snippet annotations for nginx ingress controller
- Comment out a previous configuration snippet that redirects JPG files

This update allows the use of snippet annotations, giving more control
over ingress configurations. The previously commented snippet
suggested a redirect for JPG files but is now ignored to simplify
configuration and focus on the current requirements.
