Subject: [PATCH 1/2] Upgrade/Install: Refresh update counts in the folded
 admin menu.

Top-level admin menu items repeat their update count in the submenu header, which is what shows when the menu is folded, either from "Collapse Menu" or automatically on screens 783 to 960 pixels wide. `wp.updates.refreshCount()` only updated the count in the menu link, so after an in-page update the folded menu kept showing the old count until the page was reloaded. This affected the Plugins menu, and the Themes menu in the network admin.

This adds the submenu header counts for the Plugins and Appearance menus to the elements `refreshCount()` updates.

See #66315.

Subject: [PATCH 2/2] Upgrade/Install: Test the update counts in the folded
 admin menu.

Adds assertions to the `decrementCount()` QUnit test for the count in the Plugins submenu header, which is what shows when the admin menu is folded, and for removing both counts when no updates remain.

Props robelsust.
See #66315.
