Undefined array key "deleteConfirm" prevents global debug mode setting in Contao 4.13.36

[syntaxys]

1. Installed Contao 4.13.36 with contao-owlcarousel 0.7.2 from scratch, running PHP 8.3.2
2. Tried to set the global debug mode with APP_ENV=dev in .env.local and could not connect to the database anymore
3. Response from console:
   CRITICAL [console] Error thrown while running command "contao:migrate --no-interaction -v --env=dev".
   Message: "Warning: Undefined array key deleteConfirm" ["exception" => ErrorException { …},"command" => "contao:migrate --no-interaction -v --env=dev","message" => "Warning: Undefined array key deleteConfirm"]
   In tl_owlcarousel.php line 83:
   [ErrorException]
   Warning: Undefined array key "deleteConfirm"

Solution A for users:
Add $GLOBALS['TL_LANG']['MSC']['deleteConfirm'] = 'Löschen bestätigen'; in contao-4.13/system/config/langconfig.php

Solution B for extension developer:
Change contao-4.13/vendor/respinar/contao-owlcarousel/src/dca/tl_owlcarousel.php, line 83 from
'attributes' => 'onclick="if(!confirm(\'' . $GLOBALS['TL_LANG']['MSC']['deleteConfirm'] . '\'))return false;Backend.getScrollOffset()"'
to
'attributes' => 'onclick="if(!confirm(\'' . ($GLOBALS['TL_LANG']['MSC']['deleteConfirm'] ?? null) . '\'))return false;Backend.getScrollOffset()"'
Same in contao-4.13/vendor/respinar/contao-owlcarousel/src/dca/tl_owlcarousel_slide.php, line 87

Setting the global debug mode is possible again …
