Thanks @immeet94 ! Searching through the codebase for @global wpdb, it seems there are more occurrences where wpdb misses a description. Would be great to fix also the other occurrences.

Also, when there are multiple globals (same for params), the type, varname, and descriptions should be aligned with spaces. An example would be:

 * @global wpdb   $wpdb         The WordPress database class.
 * @global string $table_prefix The database table prefix.
