feat(render): Add background task for removing temporary file

This commit adds a new parameter `background_tasks` to the `render_replay` function in the `render.py` file. The purpose of this parameter is to allow for the addition of a background task that removes the temporary file after it has been rendered and returned as a response. This helps to clean up any leftover files and improve overall system efficiency.
