`Alnum` validator too strict for `Album` names

[Tom Udding]

Current behaviour

gewisweb/module/Photo/src/Form/Album.php

Lines 95 to 98 in 637a3da

 'name' => Alnum::class, 
 'options' => [ 
     'allowWhiteSpace' => true, 
 ], 

This does not allow for -, :, ., '', "" in Album names, while this should be possible.
