Sergey Biryukov 222813317f Docs: Replace tabindex example in submit button functions documentation.
Most of the `tabindex` attributes across the admin were removed in [21311].

This commit updates the example for the `$other_attributes` parameter to use the `id` attribute instead.

Includes synchronizing documentation between `submit_button()` and `get_submit_button()`.

Follow-up to [15810], [16061], [21311], [27136], [31599].
