Feature: do not show request

### Issues - [x] I have checked [existing issues](https://github.com/rest-nvim/rest.nvim/issues?q=is%3Aissue) and there are no existing ones with the same request. ### Feature description Hi, amazing tool, using every day. But sometimes I have very big responses, over 200MB. I am redirecting them to a file with command >>! file.json but response still is shoing in the RESPONSE window. and as it is super big repsonse, it cause problems. Is there a chance to add additional flag to request to not showing this response?
