Subject: [PATCH] Plugins: Show "Activate" after updating an inactive plugin
 from the Add Plugins screen.

When updating an inactive plugin from the Add Plugins screen
(Plugins > Add New), the button remained in the disabled "Updated!"
state instead of transitioning to "Activate", requiring users to
navigate to Installed Plugins to activate it.

This updates `wp_ajax_update_plugin()` to return `activateUrl` for
inactive plugins that the current user has permission to activate,
matching `wp_ajax_install_plugin()`.

It also updates `wp.updates.updatePluginSuccess` to check plugin dependencies
and transform the button to an "Activate" link, and updates
`checkPluginDependenciesSuccess` / `checkPluginDependenciesError` to handle
`.update-now` buttons alongside `.install-now`.

Fixes #65909.
