{api,fed/in}: expose remotes claims wrt poll vote anonymitiy

Most of the major micro-blogging AP implementations do not make votes or voter identity available to anyone by regular means. However, this is but an informally adopted common practice. Smithereen may (depending on the decision of the creating user) disclose who voted and what everyone voted for. This information is made publically available to everyone, including via ActivityPub (eventhough the AP vote collections show some type and data inconsistencies between the inline and standalone version at the time of writing. It is necessary to fetch the standalone collections for the full information.) Smithereen does indicate whether a poll will disclose votes and voter identies and when this is kept secret. But of course, for this info to be visible to our users we will need to first pick up the hint from Smithereen and forward it in our Masto API responses. Example: https://friends.grishka.me/posts/1116518

@ -12,6 +12,9 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
  - Mastodon-compatible `avatar_description` and `header_description` parameters are added to account API responses and as input for `PATCH /api/v1/accounts/update_credentials`
  - `pleroma.background_image_descripption` is added to account API responses
  - `pleroma_background_image_descripption` is added as a new parameter to `PATCH /api/v1/accounts/update_credentials`
+- `GET /api/v1/statuses/:id` contains the new `poll.akkoma.anonymous` parameter if `poll` is non-null.  
+    It relays if and whether the source instance promised to keep votes anonymous or disclose votes with voter identity.
+    There are no plans to enable creating non-anonymous polls in Akkoma, but some implementations do.

 ### Fixed
 - fix date-time format in `* /api/v1/markers` to strictly conform to Mastodon’s ISO 8061 subset
