Issue title: Edit documentation for "win" case: drop token
 Issue body: <!-- Please check the Q&A before posting an issue: https://github.com/JamesIves/github-pages-deploy-action/discussions?discussions_q=category%3AQ%26A -->

## Describe the bug

The documentation here : https://github.com/JamesIves/github-pages-deploy-action#operating-system-support-

suggests to use the line 

        with:
          token: ${{ secrets.ACCESS_TOKEN }}

I believe it is no longer necessary, in this scenario the target repo is the same we are working with, so letting the token default to current session token is fine.

## Reproduction Steps

This small sample project works without specifying a token
https://github.com/yanntm/TestDeployActionWin


## Logs

Check the Actions : https://github.com/yanntm/TestDeployActionWin/actions
Or maybe the gh-pages branch : https://github.com/yanntm/TestDeployActionWin/tree/gh-pages

It works as expected without token in the https://github.com/yanntm/TestDeployActionWin/blob/master/.github/workflows/windows.yml

## Additional Comments
