add "posts" back to the admin menu

[carylwyatt]

PG removed generic "posts" from the admin menu, but we use them, so they should probably be accessible by the back-end. 🙃

We use these as landing pages for information that won't fit in a user notification. https://www.hathitrust.org/wp-admin/edit.php?post_type=post

For example: https://www.hathitrust.org/syracuse-university-login-changes-may-2024/

There are a handful of these posts, but since they're uncategorized and don't fall under "blog", "event", or "news" they're just... nowhere.

The easiest fix for this is to remove the remove_menu_page() function from functions.php, but maybe this should be its own custom post type? It's not hard to register a new CPT: pg_custom_post_types()
