Mark autocomplete as non-modal

Without this property, since react-aria 3.41.0, the value of the
input would be cleared after every keypress.

The documentation for `AriaPopoverProps` at [1] says about the
`isNonModal` prop:

> Whether the popover is non-modal, i.e. elements outside the popover
> may be interacted with by assistive technologies.
>
> Most popovers should not use this option as it may negatively
> impact the screen reader experience. Only use with components such
> as combobox, which are designed to handle this situation carefully.

Since this use case is a combobox, this should be fine.
