- adds `in_reply_to_id` to API output
- adds `in_reply_to_snippet` to API output
- dynamically generated from the HTML of the replied-to comment
- excluded if the replied-to comment has been deleted or hidden
- adds `commentSnippet` to `@tryghost/html-to-plaintext`
- skips anchor tag URLs as they won't be useful for snippet purposes
- skips blockquotes so the snippet is more likely to contain the unique content of the replied-to comment when it's quoting a previous comment
- returns a single line (no newline chars)
- allows setting `in_reply_to_id` when creating comments
- id must reference a reply with the same parent
- id must reference a published comment
- adds email notification for the original reply author when their comment is replied to

The email preheader, which is only present in the html version of an
email, is also included in the plaintext version of all emails. This
results in all text being duplicated twice in plaintext emails.
- A few users had noticed they get weird content in their excerpts when using e.g. an html block with an iframe
- This use case is common for people embedding podcasts at the top of their posts

- this shared library is standalone, and it used in various places of
Ghost core, so we can pull it out to keep it easier to reason about
- we also use the `html-to-text` dependency in another package but it's
outdated and could now switch to this new package
