feat: update RSS feed routes and logging

- Change route for RSS feed to use defaults for format
- Add logging to RssController#feed to track request format

These changes improve the clarity of the routing for the RSS feed
and enhance debugging capabilities by logging the request format.
The new route definition ensures that the feed responds correctly
with the default format, while the logging provides insight into
how the feed is being accessed.
