Use the configured storage for both announcement checks.

If storage.type is sessionStorage, the provider reads the ID and dismissal flag from session storage, but the inline script reads local storage. A dismissed bar can appear until hydration hides it. The dismissal read had this mismatch before; the new ID check can also prevent pre-hiding when a stale local dismissal flag was previously sufficient.

Use the configured storage 

-          ? `if (localStorage.getItem('${AnnouncementBarIdStorageKey}') !== ${JSON.stringify(
+          ? `if (window['${siteStorage.type}'].getItem('${AnnouncementBarIdStorageKey}') !== ${JSON.stringify(
               announcementBar.id,
             )}) {
         return false;
       }`
           : ''
       }
-      return localStorage.getItem('${AnnouncementBarDismissStorageKey}') === 'true';
+      return window['${siteStorage.type}'].getItem('${AnnouncementBarDismissStorageKey}') === 'true';

Review comment at @packages/docusaurus-theme-classic/src/inlineScripts.ts around
lines 97 - 105:
Update the announcement-bar inline script so both the ID check using
AnnouncementBarIdStorageKey and the dismissal check using
AnnouncementBarDismissStorageKey read from the storage configured by
siteStorage.type, matching the provider’s behavior. Keep the existing pre-hide
conditions and return behavior unchanged.
