Release creation fails when token is an empty string

[manferlo81]

I am using your action inside a composite action and I noticed it fails if the token if an empty string...

uses: softprops/action-gh-release@v2
with:
  token: ""

... in my case I am accepting an input named token and passing it through to your action, if the input is empty it will pass an empty string to your action causing it to fail. I solved to problem by taking into account the case the input is empty and handling myself. I believe this behavior is not the intended one, if it is, please feel free to close this issue.

I noticed you check for GITHUB_TOKEN before INPUT_TOKEN, is that what you intend?

action-gh-release/src/util.ts

Line 56 in e7a8f85

github_token: env.GITHUB_TOKEN || env.INPUT_TOKEN || "",
