using curl should suggest using vip_safe_wp_remote_get instead of wp_remote_get

## What problem would the enhancement address for VIP?
When using `curl` the suggested fix is to use `wp_remote_get`, however, `wp_remote_get` is discouraged and `vip_safe_wp_remote_get` is suggested instead.

## Describe the solution you'd like
Suggest the use of `vip_safe_wp_remote_get` when using `curl` to avoid a secondary violation for using `wp_remote_get`
