Database: Find the correct table names in DELETE queries with table aliases

Browse Source 
Previously, `wpdb::get_table_from_query()` would not find the correct table name in the query `DELETE a FROM table a`, due to not recognising the table alias immediately after the `DELETE` as correct syntax.

Fixes #37660.
