Add support for Instagram reels

[tstoeckler]

Haven't found any official announcement or documentation about this, but noticed that the new(ish) Reels feature (https://about.instagram.com/blog/announcements/introducing-instagram-reels-announcement) does not work with Drupal's OEmbed implementation. Users of the OEmbed Plus Wordpress plugin have apparently hit this as well: https://about.instagram.com/blog/announcements/introducing-instagram-reels-announcement (note that I myself am not familiar with this plugin).

Manually modifying a local providers.json to add these new URL schemes makes the embedding work fine, so as far as I can tell Instagram does support it, it's just not documented anywhere.
