DEV: Use default admin routes for plugins with settings (#30941)

This change adds a sidebar link for each plugin that fulfils the following criteria:

- Does not have an explicit admin route defined in the plugin.
- Has at least one site setting (not including enabled/disabled.)

That sidebar link leads to the automatically generated plugin show settings page.
