Hannah Wolfe 5605c964e4 🔥 Remove legacy content zero hack (#8156)
refs #7491

- this hack is so legacy I almost forgot about it 😈
- in the beginning of Ghost there were no post images
- someone figured out you could do {{content words="0"}} and it would pull out the first image in your post
- this was never documented, but enough theme developers found it that when we upgraded downsize to get rid of the bug
- we needed to add a hack to keep compatibility.
- This has to die in 🔥  for Ghost 1.0

// Turns content html into a safestring so that the user doesn't have to
// escape it or tell handlebars to leave it alone with a triple-brace.
//
// Enables tag-safe truncation of content by characters or words.
