Action updates release instead of creates new release

[mcharris]

Describe the bug
It appears that when this is setup exactly how it is in this repository, publishing to github results in the latest release being updated instead of creating a new one. As a result, you lose history of releases

To Reproduce
Steps to reproduce the behavior:

1. Release new version of this repository

Expected behavior
A new release is created on every release

Additional context
You can see this in action in this action's repo and goto releases.

@mcharris please visit https://github.com/release-it/release-it as the issue is with that project. This just wraps it into a github action.
