Twenty Twenty: Correct `label` attribute references to `aria_label` in `get_search_form`.

In the bundled Twenty Twenty theme, a `label` argument was passed to `get_search_form` but used as the `aria_label` on the form.  This change updates the argument name to `aria_label` and maintains backwards compatibility for usage of the original `label` argument.
