Wraps two aria-label strings in wp.updates.activatePluginSuccess() in __() so they can be translated:

• %s activated successfully.
• %s is active.

Both already had translators comments but were passed to sprintf() as bare string literals, so they were never extracted and are always output in English. They were introduced in [57545]. No other string in core's JS has this problem.

Note on scope: since [58250] (6.5.4) the Activate buttons in core navigate to the activation URL, so core itself no longer calls wp.updates.activatePlugin(). The untranslated labels are only reachable by plugins or custom code using that public API.

Testing instructions

1. Set the site language to a non-English locale, e.g. German.
2. Go to Plugins > Add Plugin and find the card of an installed, inactive plugin (e.g. search for "Hello Dolly").
3. In the browser console, run:

   var $b = jQuery( '.plugin-card-hello-dolly .activate-now' );
   $b.removeClass( 'activate-now button-primary' ).addClass( 'activating-message' );
   wp.updates.activatePlugin( { slug: $b.data( 'slug' ), name: $b.data( 'name' ), plugin: $b.data( 'plugin' ) } );

4. Inspect the button's aria-label.

The strings are not in the language packs yet, so to see a translated label, provide one first, e.g. wp.i18n.setLocaleData( { '%s activated successfully.': [ '%s wurde erfolgreich aktiviert.' ] } ).

	Before	After
German, translation available	Hello Dolly 1.7.2 activated successfully.	Hello Dolly 1.7.2 wurde erfolgreich aktiviert.
German, from the plugin details modal	Hello Dolly is active.	Hello Dolly ist aktiv.
English	Hello Dolly 1.7.2 activated successfully.	unchanged

wp i18n make-pot on updates.js extracts 84 strings before and 86 after; the only additions are these two, with their translators comments. grunt jshint:core passes for the file.

No unit test is included: this is a string-only change, and tests/qunit/wp-admin/js/updates.js is not currently loaded by tests/qunit/index.html.
