Changed

• The update check reads https://nibble.ink/api/v1/changelogs. The documentation site serves its release notes at /changelogs, and the feed behind them now answers on the matching address. The old /api/v1/releases still returns the identical feed, so an installation checks successfully either side of this release and nothing has to be upgraded in a particular order.
• Nibble::RELEASES_FEED is now Nibble::CHANGELOGS_FEED. The address and the constant that holds it say the same word. Upgrade: nothing to do unless one of your own files names the old constant, which only a site that reads it in site/initializers/ or a check of its own would.
