 If updating from PHP 8.0 to PHP 8.1, different variants of the following
 two errors are thrown when selecting "View details" in the plugins list.

 {{{

 Deprecated: Return type of Requests_Cookie_Jar::offsetUnset($key) should
 either be compatible with ArrayAccess::offsetUnset(mixed $offset): void,
 or the #[\ReturnTypeWillChange] attribute should be used to temporarily
 suppress the notice in /serverurl/wp-includes/Requests/Cookie/Jar.php on
 line 102

 Deprecated: Return type of Requests_Cookie_Jar::getIterator() should
 either be compatible with IteratorAggregate::getIterator(): Traversable,
 or the #[\ReturnTypeWillChange] attribute should be used to temporarily
 suppress the notice in /serverurl/wp-includes/Requests/Cookie/Jar.php on
 line 111
 }}}

 - WordPress 6.1.1.
 - All plugins disabled.
 - Tested with Twenty Sixteen and Blocksy theme.
 - No errors when downgrading to PHP 8.0.

 Please let me know if I can supply more details to help to get rid of
 these errors :)
