Is your feature request related to a problem? Please describe. We would like to promote RankMath the same way we do for WP Rocket :

• If WP Rocket isn't installed display the "We recommend you WP Rocket" in the sidebar of Imagify option
• If RankMath isn't installed display then "We recommend you RankMathSEO

Here are the content we should add for RankMath :
