PHP 8 error on Remove from Gift Aid batch

On PHP 8.1, we got a PHP error on the Remove from Gift Aid batch task. This resulted in the remove from batch form being only partially rendered, unstyled and not usable. The PHP error:

TypeError: count(): Argument #1 ($value) must be of type Countable|array, null given in include() (line 54 of .../files/civicrm/templates_c/en_GB/%%1D/1D7/1D7FFE0E%%RemoveFromBatch.tpl.php).

PR to follow.
