Rack::Input is no longer required to be rewindable in Rack 3
- https://github.com/rack/rack/blob/dff6cfd249832d32ab190e6d20605bce0d6c702d/UPGRADE-GUIDE.md#rackinput-is-no-longer-required-to-be-rewindable
When using better_errors with Rack 3, NoMethodError is raised due to trying rewind on rack.input
It should be checked #rewind is implemented before calling.
