Subject: [PATCH] fix(openrouter): list image generation in the packaged
 endpoint matrix

The proxy's public endpoint listing reads
litellm/provider_endpoints_support_backup.json, where openrouter
image_generations was still false while provider_endpoints_support.json now
marks it true. Only that value changes, since the two files already differ
elsewhere on main
