Fixes ruby-grape#2334 Ensure all header values are strings according to the Rack spec. * Convert header values to strings using `to_s` in the `header` method in `lib/grape/dsl/headers.rb`. * Emit a warning if the header value is not a string in the `header` method in `lib/grape/dsl/headers.rb`. * Add tests in `spec/grape/dsl/headers_spec.rb` to verify that non-string header values are converted to strings and warnings are emitted. --- For more details, open the [Copilot Workspace session](https://copilot-workspace.githubnext.com/ruby-grape/grape/issues/2334?shareId=XXXX-XXXX-XXXX-XXXX).
