make nginx WebP redirection (vhost image exclusion) enabled by default
Found an issue with Cloudways integration with WP Rocket plugin, particularly the image expires headers are not working. After significant investigation by Cloudways support (many thanks Ehrar for the awesome help and patience), found that the culprit is the nginx vhost overwrite that prevents the expires headers. The issue is fixed after enabling the WebP redirection in the Cloudways Application settings, which exclude the nginx vhost rules/overwrites for images such as webp, but also including jpeg, png, etc. that are needed to get the expires headers to work.
Recommend to enable it by default, seems like a situation that many users may face when integrating Cloudways with WP Rocket (or likely also apply to other caching plugins).
