Move module dependency messages from the install form to the uninstall form

Is this something we still want to do? It's been almost 10 years since the last update. My initial thoughts are this can be closed (won't fix).

I've updated the screenshots to show the current situation. The main difference is the the install form shows all dependent modules whereas the uninstall form only shows installed modules.

I'm not sure how relevant the comments are about using the information when considering updates, now that this is mostly handled by composer or package manager anyway.
