ActiveField - RadioButtonGroup with checked item on load - issue with BS 5.x

[lanceybg]

When rendering RadioButtonGroup with model that already has one of the valid options selected, ActiveField.php renders the label with 'active' CSS class added, which does not seem to be needed with BootStrap 5.x.

The result is that, whatever other option you select, the initially selected one still stays visually selected.

The fix is simple (attached .diff), but I'm not sure it does not break any other behaviour (so far haven't found any issues).

Sample code which shows the issue:

<?php
...
$types = array(1 => 'Type A', 2 => 'Type B');
$form->type = 1;
...
<?= $form->field($form, 'type')->radioButtonGroup( $types ); ?>
...
?>
