closes #39

Any other comments?

ACF Options pages are now exposed to the GraphQL Schema.

I can register an ACF Options Page like so:

if ( function_exists( 'acf_add_options_page' ) )  {
	acf_add_options_page(
		[
			'page_title' => 'My Options Page',
			'menu_title' => __( 'My Options Page' ),
			'menu_slug'  => 'my-options-page',
			'capability' => 'edit_posts',
		]
	);
}

I can then assign an ACF Field Group to the Options Page:

I will see that the GraphQL Settings for the field group map the Field Group to the GraphQL Type that represents the options page:

I can update values in the Options Page:

And then I can query the options page and the associated Field Group(s)

Bonus: WPGraphQL Smart Cache Support

This also works with WPGraphQL Smart Cache, so my queries for ACF Options can be cached and when updating an options page, queries for that options page will be purged, so we can have fresh data always!

We can see in the WPGraphQL Smart Cache Logs that purge events are happening when I update ACF Options:
