 {{{
 #!CommitTicketReference repository="" revision="61191"
 Code Modernization: Fix instances of using `null` as an array offset.

 This avoids using multisite-specific tables and columns in
 `WP_Date_Query::validate_column()` when on a non-multisite install.
 Attempting to use `$wpdb->blogs` as an array index when `null` on a non-
 multisite install causes a deprecation notice in PHP 8.5. This also
 updates the multisite table alias in `wpdb` to make it clear they could be
 `null`.

 Developed in https://github.com/WordPress/wordpress-develop/pull/10498

 Follow-up to [60904], [60809], [37477].

 Fixes #63957.
