TwitterCard meta tags are supposed to use the attributes "name" and "content".
OpenGraph tags use the attributes "property" and "content".
Twitter itself is smart enough to detect broken meta tags and discover the TwitterCard
using "property" and "content", but other platforms that only implement parsing of TwitterCards
and not OpenGraph may fail to correctly detect the tags as they're under the wrong attributes.

This brings them more in line with Mastodon.
- Deduplicates display name from the title and content
- Removes arbitrary limits on the size of the embedded image
- Removes angled double quotes from embed descriptions. These would normally just indicate that the content is a quote, but that is already implied by the content being in an embed.
