FIX: Unscoped plugin config page actions outlet (#29026)

In 61c1d35f17 I added a
PluginOutlet to AdminPluginConfigPage. This was intended to be
used as a way to render actions buttons inside the header of
a plugin that has a custom admin UI page. This worked, but
since the outlet was generically named, as soon as one plugin
used it the button would show on all plugins.

This fixes the immediate issue by naming the outlet based
on the plugin, then having each plugin specify their own
outlet to render into. There may be a nicer way to do this,
but for now this stops the bleeding.
