Add support for Jetpack open graph tags in AMP stories

[spacedmonkey]

AMP Stories are a custom post type in the AMP Plugin.
However, the template does not use call wp_head, so the OG tags generated by jetpack are not inserted. AMP stories has a custom action amp_story_head which performs a similar action, introduced in ampproject/amp-wp#3039 .

Describe the solution you'd like

A solution for this should be pretty simple. In the case Jetpack_AMP_Support there is already a hook into amp_post_template_head to add og graph tags in this line.

// include Jetpack og tags when rendering native AMP head
add_action( 'amp_post_template_head', array( 'Jetpack_AMP_Support', 'amp_post_jetpack_og_tags' ) );

Add support for amp stories could be as simple as adding the following code.

add_action( 'amp_story_head', array( 'Jetpack_AMP_Support', 'amp_post_jetpack_og_tags' ) );
