Add permission for replacing own files

Hello and thanks for adding this feature,

I tested the new patch on Drupal 10.2.5 and Php 8.2.7. The access logic did not worked as expected. The code below have to be changed:

$is_owner = (bool) $account->id() == $file->getOwnerId();

to

$is_owner = $account->id() == $file->getOwnerId();

bool cast have a problem i think. Overall the patch worked after that. I am also adding the revised patch ( add_permission_for_own_files-r1-240426.patch → ).

Best regards,
