Workflow needs write release permissions

[StarTrooper08]

Hey HF team,
Thanks for creating such an awesome actions.

I was trying to use this actions but due to permissions needed to write release it wasn't working.
This need to be mentioned in readme(might be helpful for beginners)

Here's how I've used it
