Config to comment coverage results in a <details> tag

Hi @mattallty 👋

Great GitHub Action, thanks! What do you think about creating a config flag to enable coverage reporting as a comment using the example below. In this way the overall comment can be collapsed and doesn't overflow the screen if one has a lot of files. (similar to how https://github.com/ziishaned/jest-reporter-action works)
