Use javascript/ajax for reset plugins button in admin

[CodeProKid]

The button is currently super wonky. It just links to the current page with some url params that I use to execute the Dictate::reset_plugins(); method, then it resets the page with: header("Refresh:0; url=" . admin_url( 'plugins.php' ) ); 😆

Ideally, when you click on the button it will add the spinner next to it, run the method via ajax (or maybe I'll add a REST endpoint) and then refresh the page.
