Modify send email copy checkbox in contact form

Pull Request for Issue #34757.
Probably not the best solution, but the only one a I can think at the moment.

This problem is related to #31218 and is something we need to reconsider for the next major Joomla version.

The problem with this is that it only fixes this one field. If you have another checkbox type field on that page then you still get the problem.

From what I can tell it needs a display:inline-block on the .controls class

[drmenzelit]

display:inline-block is not enough, because .controls is inside .control-group together with .control-label
If .control-group would have another unique class for the copy field, one could use display: flex ... but that is not the case, all fields have only .control-group...

Please check #39259

If you change your condition to

<?php if ($field->type != 'Checkbox') : ?>

the form can have many checkboxes.

This functionally should be removed completely instead of fixing it. I close this PR since allowing the user to send emails to an arbitrary address is a security issue.
