Incorrect Accept header used #23
Description
I tried to use this gem with the rails_admin gem and hit a problem. When a file is modified and hotwire-spark makes a request to the server to get the new content it uses the fetch function in JavaScript. When Rails receives the request the Accept header is set to */*. This causes rails_admin to render the page as JSON due to the order of how the formats are specified in respond_to [1].
I'm arguing that this is wrong (or at least unexpected) behavior. But rails_admin works when used normally in a web browser, because the web browser always sets an explicit Accept header to text/html. So I'm also arguing that hotwire-spark should behave as close as possible to the actual web browser when making requests and therefore should set an explicit Accept header.
