FIX: Improve admin plugin list and modernize code (#23256)

This commit contains a few improvements:

* Use LinkTo instead of a button with a weird action referencing the
  controller to navigate to the filtered settings for a plugin
* Add an AdminPlugin model with tracked properties and use that when
  toggling the setting on/off and in the templates
* Make it so the Settings button for a plugin navigates to the correct
  site setting category instead of always just going to the generic
  "plugins" one if possible
