Bug description

freshly updated NC 28.0.4. I get a lot of errors like this one:
is_file(): open_basedir restriction in effect. File(/usr/share/nextcloudapps//core/l10n/fr.js) is not within the allowed path(s): (/usr/share/nextcloud:/var/lib/nextcloud:/var/log/nextcloud.log:/var/lib/php/nextcloud:/home/x/x/nextcloud) at /usr/share/nextcloud/lib/private/Template/ResourceLocator.php#100

server is installed under /usr/share/nextcloud and not /usr/share/nextcloudapps/ looking at the code
if ($root !== false && is_file($root.'/'.$file))
it seems that $root gets wrong

Steps to reproduce

1. upgrade nextcloud to 28.0.* from NC 27
2. see the nice alert "49 erreurs dans les journaux depuis 1 avril 2024" growing
   3.check log

Expected behavior

no error reported
NC root detected correctly
