Using a `data-toggle` attribute, which we do since commit 07fd5084f,
made Foundation generate an `aria-expanded` attribute to a radio button,
but this attribute can't be present in radio buttons. This makes sense,
since the main purpose of a radio button in a form is to choose an
option, not to show/hide content.
This resulted in the following error when checking the page with Axe:
```
Found 1 accessibility violation:
aria-allowed-attr: Elements must only use supported ARIA attributes
(critical)
https://dequeuniversity.com/rules/axe/4.10/aria-allowed-attr?application=axeAPI
The following 2 nodes violate this rule:
Selector: #dashboard_action_action_type_proposed_action
HTML: <input data-toggle="request_to_administrators short_description"
type="radio" value="proposed_action" checked="checked"
name="dashboard_action[action_type]"
id="dashboard_action_action_type_proposed_action"
aria-expanded="true"
aria-controls="request_to_administrators">
Fix all of the following:
- ARIA attribute is not allowed: aria-expanded="true"
Selector: #dashboard_action_action_type_resource
HTML: <input data-toggle="request_to_administrators short_description"
type="radio" value="resource"
name="dashboard_action[action_type]"
id="dashboard_action_action_type_resource"
aria-expanded="true"
aria-controls="request_to_administrators">
Fix all of the following:
- ARIA attribute is not allowed: aria-expanded="true"
```
So we're using custom JavaScript instead. We're also making the
`short_description` field act as intended; since the changes in commit
07fd5084f it was never shown because it had the `hide` HTML class and it
didn't have a `data-toggler` attribute.
