BUG in form_hidden with associative array

[bvrignaud]

There is a bug in the form_hidden function declaration.

In the documentation (https://bcit-ci.github.io/CodeIgniter4/helpers/form_helper.html?highlight=form#form_hidden) we can read :
You can either submit a name/value string to create one field:

form_hidden('username', 'johndoe');
// Would produce: <input type="hidden" name="username" value="johndoe" />

... or you can submit an associative array to create multiple fields:

$data = array(
        'name'  => 'John Doe',
        'email' => '[email protected]',
        'url'   => 'http://example.com'
);

echo form_hidden($data);

But the second way doesn't works.

The second parameters ($value) must have a default value.
