Docs: Remove the legacy example of passing a taxonomy to `get_terms()`.

As of WordPress 4.5, taxonomies should be passed to `get_terms()` via the `taxonomy` argument in the `$args` array:
{{{
$terms = get_terms( array(
    'taxonomy'   => 'post_tag',
    'hide_empty' => false,
) );
}}}

The legacy way of passing a taxonomy via the function's first parameter was still mentioned in the documentation, causing some confusion.

This commit updates the function documentation to better highlight the currently recommended approach.

Follow-up to [36614].
