* Add og:image:width, og:image:height, and og:image:type tags.
* Use og:video tags for videos.
* Use 720x720 instead of 150x150 preview images for videos.
* Add duration tag to JSON-LD data for videos.
* Add OpenGraph tags to media assets show page.
* Respect Twitter max image size limits.
* Don't include OpenGraph image tags when someone shares a plain https://danbooru.donmai.us link
with no tag search. This caused random potentially NSFW images to be shown when someone shared a
https://danbooru.donmai.us link on social media, which could be cached for long periods of time.
For small thumbnails, use 180x180 thumbnails scaled down to 150x150.
This is so we can get rid of 150x150 images and just use 180x180 for
both small and medium size thumbnails.
Also fix RSS feeds, XML sitemaps, and Discord embeds to use 360x360
thumbnails instead of 150x150 thumbnails.
