Add internal link from "Install plugins" to the Favorites add-on (if installed)

On this page: /wp-admin/admin.php?page=PluginsInstall

under the tab “Install from Favorites”

There should be a link similar to:

"You can manage your favorite plugins [here](/wp-admin/admin.php?page=Extensions-Mainwp-Favorites-Extension)"

I can't tell you how many times I've struggled to remember or find where that list of favorites is maintained while I’m at that first URL.

Aside:

Also please add a translation to change “🇺🇸 Favorites” to “🇨🇦 Favourites”
