html_entity_decode() expects parameter 1 to be string, array given

Bug description

We've update to klaro-consent-manager 1.3.0 yesterday.
After the update our website was not more accesible because of an internal error.
The log was flooded with the following entries:
request.CRITICAL: Uncaught PHP Exception TypeError: "html_entity_decode() expects parameter 1 to be string, array given" at /contao/vendor/pdir/klaro-consent-manager/src/Hooks/GeneratePageHook.php line 262 {"exception":"[object] (TypeError(code: 0): html_entity_decode() expects parameter 1 to be string, array given at /contao/vendor/pdir/klaro-consent-manager/src/Hooks/GeneratePageHook.php:262)"} []

Steps to reproduce

Upgrade to klaro-consent-manager and try to open the web page

Expected behavior

Website comes up

Screenshots

Environment

PHP 7.4
Contao 4.13.38

Bugfix

We've located the error in commit 7f67496 in src/Hooks/GeneratePageHook.php

We've changed line 261 in src/Hooks/GeneratePageHook.php from
array_walk($arrCookies, static function ($cookie) use (&$arrResult): void { $arrResult[] = html_entity_decode(str_replace(''', "'", $cookie)); });
to
array_walk($arrCookies, static function ($cookie) use (&$arrResult): void { $arrResult[] = html_entity_decode(str_replace(''', "'", $cookie['key'])); });

after this patch the website operates normally.
