Requests_Utility_CaseInsensitiveDictionary::getIterator() should either be
compatible with IteratorAggregate::getIterator(): Traversable, or the
#[\ReturnTypeWillChange] attribute should be used to temporarily suppress
the notice in /wp-includes/Requests/Utility/CaseInsensitiveDictionary.php

 Here is the fix:

 {{{
 public function getIterator(): iterable { // Add 'iterable' to the return
 type
     return new \ArrayIterator($this->data);
 }
 #[\ReturnTypeWillChange] // Add the #[\ReturnTypeWillChange] attribute
 before the method declaration
 }}}
